Love a good old bit of CAD: Cardboard Aided Design! :D
As for the rubber, door weather stripping for cars work great
Tin snips/sheet metal shears. Also, you absolutely need to prime & seal the holes you drill into the car (if you didn't do that already) so that they won't rust. Even in a dry/dry-ish climate there will be moisture at some point and it will invade those unprotected holes. Rust Never Sleeps. Your heat shield looks great by the way!
Mike D Hey thanks for the tips! Didn’t even think of that.. I’ll have to go back and seal those holes 👍
Pro tip, you can use blutack or play-doh for clearance checking as well. Stuff the putty on it and then close the bonnet :)
Genius!! Thank you!!
i was thinking of taking a level on a 2x4 across the fender surface where the hood meets it but this would be more exact. but i guess the foam would take care of minor miscalculations
Great idea and use of resources. Great payback for the cost involved and tremendous for DIY car people. Thank you!
I’ve always enjoyed making things work on my own. Totally appreciate your effort. Thanks for keeping it clean, God bless you
Now THAT'S a how to do it DYI vid!! Excellent amount of detail, thanx 4 not skimping on any info 👍🏻
That tape high-spot trick was SWEEEEEET! Great job man this was awesome, definitely going to be my weekend project now.
Thanks man, it's gone a be my next project. Because of you now know i know the right way to do it my own custom p-flow box.
GOOD TIMING. 👍👍2 hrs ago I was sitting here planning my custom CAI.
with patience comes success .great job!!!
good ideas and done with general shop tools!!! ima give this way a shot thanks!
Great job, those pop nuts are brilliant! Cheers mate!!
sick job mate
Awesome ideas!!!! Really impressive 👏🏻
Fantastic! This gave me some great ideas💡👍
You sir, have earned your PhD in garage engineering!
New Sub too
Well done. Definitely enjoyed the whole process. Will make something like this also, but with a top cover (rain cover) coz my hood has vents. Keep up the great work 💪🍻
Wow it looks fantastic. Definitely going to be making one of these for my speed3 soon. Just can't justify spending the money on the corksport one if I can just make one myself that works just as well.
Nicely done i did something but i use bookshelf hangers they vome n 3 different sizes but i like the gas hose trim i wasn't for sure what i was going to used on the edges so tks for content
Awesome video thanks for sharing you really helped me with this great idea 💡 thank you 🙏🏻 sooo much 🇦🇺👍🏻 you did a great job..
Very cool DIY idea. I will definitely take on this project for my vehicle. Thanks.
Great im planning to do one to upgrade. The intake from my 2011 chevy Colorado right now makin the design to improve the one that sells k&n didn't found one from another brand. Thanx Saludos desde Ensenada México 🍀🎶🍻😉
In my opinion it's best to have a big airtight airbox directly routed to the front of the road, but I must say it's nice build man,good job !
Im gonna be modding my CAI intake by swaoping out the filter with a 6 in velocity stack and i need a heat shield thanks for the tips
Very professional man well done
This project was sick, that's all I'm gna say. Gna be starting mine soon.
Big help, thanks!
Wow looks awesome man, well done!
I have to say this was one the best videos I've seen for DIY stuff...Definitely worth the 16 minutes!!!!!!!!!!!!!!! And great idea with using the blue tape to see where it stuck to the hood!!! Doesn't it just feel great to do your own custom work even if it takes some time?!!!!! KUDOS MY MAN!!!!! :) ;)
Thank you!! Definitely happy with the outcome!!
@@_GarageThings More than welcome!!!
Black door-edge molding would’ve been best vs the gas line… overall great tutorial with the DIY heat shield
Good job..very resourceful
Thank you very much! Really informative video.
Good job very industrious
What a great build and video! Does the shield reduce the sound from the intake at all?
Halfway in I thought I was watching a shitshow but it ended up looking very nice and pro. Great job.
Lol Thank you.. I felt that way too after watching this again.. The zip-tie clearance technique was pretty dumb in hindsight
man that came out looking really freaking good. I remember on my first car back in high school I decided to make my own intake heat shield out of cardboard wrapped in aluminum foil lmao. Needless to say yours looks (and probably functions) 100 times better than mine did
Thank you!! I've done some suspect mods back in high school as well.. You're not alone!! Lol
Lol how did the cardboard not catch on fire
You have a new subscriber sir!
nice job, well done.
When the hood get close , there's a hot air also sunction by the air filter
Great job
Thanks!
Great video so much cheaper then buying a heat shield
Great video. I need to make a heat shield myself, but unfortunately patience and finesse aren't my strong points. Definitely looks doable though.
So auto shop payed off in Hi School. That's a very nice job.
Very good job.
Good job bro. I'm already make heat shield with fiberglass. Now just put CAI for it. That makes it better.
ingenious!
thanks for the ideas
Nice video about to do something similar on my car.
Nice job!
Great job!👍
Thank you!
Brilliant!
that's amazing top stuff !
TinSnips might work a better for sure. The siding your house type. 👍🏻💯 #goodwork
Awesome video
this convinced me its worth the extra $90 to get the intake for my car that includes a heat shield LOL
most of the shields that ive seen suck a LOT of engine air.
You could also wrap the intake pipe in silver tape.
What type of material is good for the airbox. Would be better for it to not be easily melted and also not be extremely hot when at long drives
6:32 music feels like I'm about to select my garage on the map of GT2
Good idea.i can make my own in take cover.TQ
I like cool air up my nose in the evenings also.
Great job, be careful that is earthed to the car now . Make sure it doesn't give you problems.
Very well done my friend. Now get u some medical grade water activated fiberglass ina roll and make it from composite! I’m doing an intake now for a bmw 328i and and all in I’m at $60 or bucks. Not bad compared to $400!
so I have the short ram intake (aka hot air intake) & besides thin sheet metal, what other stuff would I need to start making a heat shielf? (yes I'm aware I'll also need high temp paint & a heat barrier)
Wow, nice attention to detail.
Good information and workmanship, well done !
I'm very fan of diy this is amazing I just need to buy extra tools that the ones I already got
Doing the exact same thing 👍
2 thumbs up 👍 👍 bro
Nice.
AWESOME AF .....
love the thumbnail 😂😂
Where did u get the flexible rubber protection on the upper lip ?? Thanx
Uuh sorry i missed that part now i know!
If any one knows the correct rubber band that goes on the upper edge let me know please! N i will share my design with u.
Blessings!
Yo, you did an awesome job!! The measurement techniques seem invaluable! I'm definitely going to do this for my '99 ES300!!!
Hey thank you! Ya I honestly could have done better with my measurements (especially between the shield and hood).. Spending extra time measuring will definitely show in the end.. Good luck!!
@@_GarageThings I'll have to update you when it is completed!!
@navydad82 hey I have an 01 es300, how did this turn out??
smart kid!!!
Looks great, where is it actually pulling air from though? It looks like you sealed it off too well?
Thanks! Ya that was a concern I had too! Some air comes thru from near the upper right side of the radiator (facing the car).. there is also a hole under the headlight housing, pulling air from the front of the wheel well/bumper area.. I just recently fab'd up a vent hose to take air from the front bumper inlet and direct it thru that hole.. It seems to work well
This guy secretly works for k & N
Very nice video! Maybe the best one I found. But where is the air coming from? because the filter is now almost boxed / closed when closing the hood. Kind regards, Xander
Through the bumper

The sad part is, after all that dedicated work, it's been proven the dyno'd HP and TQ difference with CAI's is not even substantial enough. It may definitely "sound" better but the stock airbox with a K&N FILTER is thee fastest and most cost effective improvement.
k&n filters are trash, not only does the oil from them get sucked into the sensors and throttle body but their filtering efficiency is laughably bad compared to a standard oem paper filter.
@@ryanfrizz - K&N filters or dry BC filters, whatever you like John, either way go online or watch a few TH-cam videos, you will see dyno runs showing CAI kits making very little improvement at all compared to stock air boxes with aftermarket filters
Thanks for the input!! You are correct sir! I'm sorry if you were looking for info on making large HP gains :/ (try searching "forced induction") However, after all my dedicated work, I did happen to learn something about basic fabrication and I managed to keep some hot air out of my current intake setup. Personally, that's a win-win!
@@_GarageThings - AMEN brother! Huge respect for taking on the task of fabricating and building something from scratch you can call your own! Those are projects and experiences you will always learn from! Keep up the hard work and the motivation - definitely a win-win!
@@jagplaha9959 Thank you!! :D
tabs were genius
I want to get a cold air intake for my '96 corolla but want a heat shield so the heat from the engine doesn't stick to the filter (obviously)
but the way the factory air box is designed looks kinda strange, it has a hole on the bottom (under the factory drop in filter) but it leads to something & idk what it does exactly
would I need to remove it if I ever make a DIY heat shield for the cold air intake?
it uses clips to the hold the whole air box down
Usually the hole under the factory air box will have a plastic tube attached, directing air to the intake.. Sometimes, these are removed and misplaced.. That could possibly be what happened to yours
I couldn't tell you exactly without seeing it.. But I imagine, you should remove all the airbox components if you are replacing it with a aftermarket intake system..
@@_GarageThings it still has that tube
just don't know I would mount one without it hanging kinda loose cause it sits a little higher above the transmission
@@_GarageThings finally decided to buy the intake
will it be difficult to build one though? I obviously don't want engine heat to stick to the filter
Thank u
Dude that’s awesome I’ll pay you to build me one lol
I wish you could make on for me 🤣I have an 2013 audi a6 3.0t but I don't want to spend $300+ for a intake system
Good options for intake systems are the cts and k&n intakes they range from $250-$280 but honestly pick up a spectre intake from Autozone and slap it on to your oe maf hose/intake hose you’ll get all the sounds that the expensive systems give you minus the heat shield then you can just follow this video for the shield good luck!
If my engine is pretty far from my air filter do i still need the heat shield? My car is a Seat Leon 1M 1.9 TDi 150 hp it this is going to help if you want to see their positions under the hood. Sorry for my bad english
I'm not familiar with that application.. Generally, if your air filter is in a location that gets heat from another area, it would help to create a barrier to stop some of that heat.. I suggest checking the forums and asking other ppl with the same car.. Hope this helps!
@@_GarageThings gcdn.polovniautomobili.com/user-images/thumbs/1895/18954579/5c42c11f2eec-800x600.jpg hope that this photo will make you to get an idea over it
So in essence you've gone from a factory airbox with cold air intake to an aftermaket pod which then needs heat shielding!
And I couldn't be happier! I've also, upgraded my suspension - in essence, removing my factory suspension (with struts and springs) and replacing it with aftermarket suspension (with struts and springs)
But good news for some people - you don't have to upgrade or modify your car if you don't want to!
You could use a nibbler drill attachment to cut thin metals quickly they are the bomb
This would have made things a lot easier!! Thank you!!
You could make the templates available online.
Hey what was that tubing you used for the edges? And is it fairly heat resistant?
It's a fuel hose which is fairly heavy-duty rubber.. Most any plastic or rubber would be ok [in the engine bay] as long it's not touching the exhaust manifold or anything else that could melt it
I'm just gonna reuse my airbox to cover the back. That'll work
Link to that cold air intake?
👍
What were the gains?
I looks like it still draws air from engune bay which is hot
My intentions weren’t to make HP gains.. the goal was to create a barrier between the hottest area in the engine bay (exhaust manifold) and the intake filter in hopes to draw in less hot air and essentially not lose HP from the heat
There is an opening allowing cooler air from in front of the filter to the main bumper inlet, so that helps too
According to the butt-dyno, there’s a noticeable difference, especially on hot days and long drives. It seems that the car isn’t being “choked” with hot air, if that makes sense
Hope this helps!
@@_GarageThings nice seems legit. I thought there was no hole for ambiente air to come in. Ima do something similar to my car ive been seeing a lot of positive feed back and ita cheaper amd better than a cai
This seem like it took you some time and more money to get it done than just buying the box, was it worth it?
Great question! Prior to making this, I hadn't even checked to see if K&N made a plug-and-play option for my Miata. I just wanted to make something haha
But I should have included build costs in the video. Here's a rough breakdown of the materials as I remember:
Vent Pipe - $15 (home depot)
Stick-on Heat Wrap - $18 (amazon)
Aluminum brackets and Hose - $5 (home depot)
Paint - $0 (already had it)
Total for materials = $38
I already had all the tools aside from the Rivet tool ($5) and Rivnut tool ($25, both from harbor frieght), which I see as somewhat of an investment since I get to use these in the future.
After a bit of searching, it appears that K&N does not make a heat shield for my application. But I did see comparable heat shields for other intake brands are around the $100 range.
Would I recommend building over buying? It depends.. If you want to save a few bucks and you have the tools, confidence and will to build it, then go for it!! Or, you can spend a little extra and buy it..
But I should add, it is VERY satisfying seeing something I built every time I pop the hood :)
my question is if i NEED a heatshield?
Can i know the thickness of the aluminium that youre using?
26 gauge galvanized steel
with the labor time , not only your actual labor time but the video editing time ! .. u have prob. close to 20 hrs maybe 30 into this thing with the video editing .. utube is getting alot of free video work !!!
Would be at all beneficial to add the heat wrap on inside the box as well
I suppose it wouldn't hurt to have it on the inside.. but from what I understand, the wrap is suppose to be facing the direction of the heat to reflect it
Where does it get its air from if its covered
Air comes in from an opening at the front where the radiator is.. also an opening under the front headlight where I routed a 3" flex hose from the bumper air dam.. This forces cool air into that space.. It actually makes a big difference! I've been meaning to do a video on that
TH-cam performance air filters dyno tested. The stock ones perform much better
Thanks for you comment! The videos I'm seeing generally lean toward a slight hp gain with the aftermarket filters and cold air intakes. Please do share a link if you can!
But regardless, aftermarket intakes are certainly not the way to make any significant extra power. So why do so many people use them? As the hp gain/loss (depending what side of the fence you're on) is negligible, it boils down to personal preference. Personally, I like the way it sounds. To me, the sound of an aftermarket intake and exhaust enhances the driving experience.
It is a little like saying Asian people are more attractive. Some are, some aren't. The same is true of aftermarket intakes. Some are a huge improvement, some are way worse. It is physics though, does airflow increase or descrease? Does IAT(intake air temp) get hotter or colder vs AAT(ambient air temp)? Does the filter clean the air(super important if you have a turbo)? If your aftermarket intake improves all of those, its going to be an improvement. But if it only improves one and makes the other two worse... judge each intake on the merits, the one you made looks great!
@@jlaustill Great points all around and your comment made me lol as well so thank you sir!! Hats off :D
@@_GarageThings I've found my subaru impreza making a crummy intake sound after i bought it. Looks like the previous owner tried to delete the resonator chamber behind the wheel guard but didn't and left it there with the bracket it should sit on missing making it shake at make the sound it is. As well as some bolts and trim clips on the way to installing the air intake missing (how i located where the sound was coming from) So i can't find a wreckers with this bracket or somewhere to purchase it and am considering an aftermarket CAI PURELY TO FIX THE SOUND. Heat sheild DIY was awesome nice work.
I definitely feel the engine choking and delaying when it makes the sound between 2000 and 3000 revs before its kicks into a clean acceleration and doesn't have the sound.
@@_GarageThings what annoys me is the people that expect 50hp gains from a cai then get disappointed and proceed to shame anyone using one...
Id never put that on my 370z. Just going to let a bit more air in and it won't be as filtered as the stock filters. The thing is if you can see through the filter then don't use it. Mine as well just go without a filter. Not worth a 5hp gain lol
Hi, thanks for your comment! But you may have missed the point of this video - how to make a heat shield, to avoid heat soaking your engine
If you are looking for HP gains, try searching "forced induction" Cheers!
How thick is the metal sheet??? Any idea??
26 gauge = 0.45mm galvanized steel
