This video was amazingly helpful! My #4 spark plug and ignition coil were both blown and no mechanic shop were open over the weekend. Got everything from my local parts store and did it in my driveway with this video. 😸
Got any pics of the spark plugs and ignition coil? My #4 cylinder is misfiring and hoping that this is the issue and something causing a compression issue (head gasket, piston rings, etc).
Thank you I used another video with the is 250 thinking I had to remove the intake to get to 2 ,4,6 coils. Almost stripped hex bolt this was very helpful. Thanks again
Thanks for showing how to do the hard side (the Driver's side)! This was the 4th video I watched and none of them wanted to show this. The Passenger's side is a piece of cake. Thanks again.
I was tech at lexus the year these came out but left. I told my buddy id come change his coils so im looking up the engine bay to refresh myself and EVERYWHERE says YOU HAVE to remove the intake and im thinking... I KNOW i never had to do that at flat rate... Thank you for posting this and letting me know i wasnt crazy lolol
@@krlm2280 no.. The 250 has an extra bracket that covers the 2nd plug. Theres no way around taking the intake off. You only need to get it loose and then shift it to the side for about 10 seconds. Its super annoying. Be careful with the bolt on the BACK of the intake! Im having an issue with one right now.
Lexus wants $768 to do this job! I bought the plugs without knowing how hard it would be…glad the IS isn’t hard too hard to do! Over $700 in labor-woww-hanks so much for this video!
I just finished changing the spark plugs. But I did it the hard way : / I took off the manifold and it was one of the hardest things to do, because of the screw that's hiding on the backside. The easy way to take off is a power tool, because of the confined area. If I would have seen your video I would have finished in no time. Thanks for this video till next time I need to change the plugs.
Thanks for this vid, helped me a lot! Was a bit annoying to get some of those plugs lose, apart from that it was fine. And to those who don't have a swivel socket, a little wrench (preferably ring wrench) works too for those annoying ignition coil bolts! It's a bit tricky but it works.
nvm bro holy sh*t after commenting this i got it to work! still waiting on my ignition coils to come in but i wanted to make sure i could replace it! thank you
Can someone drop like a layout of all the things you need aside from the spark plugs? (Any type of tools that have special diameters that are needed to complete this job)
A crows foot wrench on an extension to break them bolts loose under the manifold works wonders too you can get a set of metric crows foot wrenches at harbor freight for like 12 bucks it also comes in handy tightening them down
I forgot to disconnect the camshaft sensor wire harness and I damaged it pulling too hard. Anyone reading this make sure to disconnect the sensors like in the video. Saves a bunch of headache since the wire is very short.
Much easier on the IS350 than it is on the IS250. Taking the intake off the IS250 added like half an hour to the job which should have been 30 mins max. Too bad there are no 350s here.
Nice video Found oil on one of the coilpacks. Had valve cover gaskets replaced a year ago. Can i get away with replacing just the seals/tubes for the spark plugs ? Can i do that without pulling valve cover off ?
Hey i just have a single code for a cylinder 4 misfire on my 08 gs350. was wondering what the torque specs are for the ignition coil as that’s all i have to replace 🙏 or is hand tightening it fine
@@RodriguezRepairs thank you i figured that out it ended up just being the ignition coil easy fix! also found a way quicker way to do the right bank! you just unscrew 2 10mm bolts, then you can reach all 3 ignition coils, instead of disconnecting all the camshaft sensors like you did in the video. figured that out because the camshaft sensor wouldn’t disconnect and i had to find an alternative
apparently on the 2nd gen is250 they say you need to remove the intake which I dont think I would want to do lol I wonder if it would be worth also just replacing the coils at the same time
Do not use anti-seize or lubricant on NGK spark plugs. It is completely unnecessary and can be detrimental. Corona stain is a light brown or tan discoloration on the outside of the ceramic insulator above the metal shell/hex - From the NGK website.
TH-cam should have recommend this video earlier. I just sent my car to workshop to replace the coil. 2 hours job as the Mechanic removed the intake manifold for access.
for the IS250 if there isnt any clearance for the coils on the bank the intake sits on, the you gonna have to take the bolts of the intake out just enough so you can lift up the manifold to take the coils out
Well that's the thing, some mechanics have always used it, and some swear against it, most modern spark plugs will contain a coating on the thread to protect against corrosion and seizing of the plug but depends on manufacturer and brand. So in my opinion, a small amount is fine as long as you don't over torque the plug.
that means that the spark plug valve cover seals are worn out which is letting oil seep through the threads. your valve cover gasket needs to be replaced
Yes i am aware, it is because it can alter the torque values in result, they can be over-torqued but as long as only a small amount is used, it should be fine. Also NGK has a special coating on the thread to help with corrosion
Yes most vehicle plugs are pre gapped unless its a vehicle from the 90s or below. I always verify the gap just incase the spark plug might have been dropped or mishandled in the delievery that it closed the gap from spec
yes the plugs come pre gapped so you dont have to worry about calibrating them BUT sometimes the new plugs are dropped during shipment which can bend the ground electrode
@@RodriguezRepairs they where all good when I put them in. Question tho do you have to break them in? Cause I installed them and first day there was a lag when flooring it.. They have to adjust? I don't recall Denson plugs doing that!
It seems the intake manifold is different from my IS… I have an additional bolt from the intake manifold that secure to the engine, covering spark plug 4.

oh cool, no need to take out the intake mani! this helped big time. i was freaking out about having to take out the manifold.
im glad i could help!
Yo foreal!! I was getting ready to take it all out when I found this video 💯💯
Yes. Great video. Thanks for sharing!
Great video , I’ve seen seen videos where people take off the intake manifold. Life saver , time saver .
Thank you so much for this video. And here I thought you had to remove the intake manifold for bank 2! Awesome!

That's the best way of replacing the spark plugs bro. Thank you
I'm glad you were able to get the job done!
Very useful and clear video thank you.
Glad it was helpful!
Very thorough video. Thank you!!
Thank you sir. Big help!
Im glad i could help!
AWESOME, thank you, I always thought I have to take the air manifold out.
Very helpful tip. Thanks alot.
No problem! Im glad you found this video useful!
Thanks for the guide!
No problem!
First guy who knows what he’s talking about! You don’t have to remove the manifold !
Thank you!
Excellent 10/10 video
Awesome video. Do the coils need to go back in the same order?
Thank you. JC
NGK says not to use anti-seize on their spark plugs
The only reason its not recommended is because the risk of thread damage by overtighening. If you tighten to spec, you should be fine
Great instruction!!
Thank you! im glad i was able to help out!

Thanks dude very helpful
How reliable are the 2006 IS 350?? Want a mechanics honest take
I beat the hell out of Mine, currently have 220k miles. Just keep up with Maintenance, you'll be fine
Much easier on the IS350 than it is on the IS250. Taking the intake off the IS250 added like half an hour to the job which should have been 30 mins max. Too bad there are no 350s here.

No, you must remove the valve cover to replace the spark plug tube seals.

Appreciate it man
Hey i just have a single code for a cylinder 4 misfire on my 08 gs350. was wondering what the torque specs are for the ignition coil as that’s all i have to replace 🙏 or is hand tightening it fine
For the ignition coils, you can just tighten them with a 1/4 in ratchet
@@RodriguezRepairs thank you i figured that out it ended up just being the ignition coil easy fix! also found a way quicker way to do the right bank! you just unscrew 2 10mm bolts, then you can reach all 3 ignition coils, instead of disconnecting all the camshaft sensors like you did in the video. figured that out because the camshaft sensor wouldn’t disconnect and i had to find an alternative

That helped a lot bro good vid
No problem! glad i was able to help
In what cases do you need to turn to a specific force with torque wrench?
Wait how did you remove the coil for cylinder 4!
The manifold nipple and a solid line on the otherside prevents this!
NGK doesn’t recommend any anti-seize on spark plugs!!!
Wire harness clip. What exactly did you do to get it out?
5/8 spark plug socket?
apparently on the 2nd gen is250 they say you need to remove the intake which I dont think I would want to do lol
I wonder if it would be worth also just replacing the coils at the same time
hmm are you sure? I believe you can use this procedure on the is250 as well!
@@RodriguezRepairsno I am not it was shon in a few othe rvideos I watched whic hto me I really wouldnt want to have to do that if Iwoens a is250
Reminds me of how i did my wrx on the drivers side haha.
Do you know where the intake temperature sensor is, the code the scanner gives me is p0113
the intake air temperature sensor is integrated into the mass air flow sensor
What about the gap for the SP

Sorry about that experience! subscribe for more videos!
The is250 setup is different and has to be removed
yo bro can you please tell me the name of the 10mm swivel socket!! i got one but it was too thick at the base. thank you so much
yes bro it was the Snap-On slim swivel socket set!
@@RodriguezRepairs was it a quarter inch driver? i was using a 3/8 and it didn’t work
nvm!! found a way to get it out with just a 10mm ring wrench, thanks to another comment on the vid. big thanks 🙏
Is it the same for the IS250 or do you have to remove the manifold on the 250? Thanks for the video.
for the IS250 if there isnt any clearance for the coils on the bank the intake sits on, the you gonna have to take the bolts of the intake out just enough so you can lift up the manifold to take the coils out
Great video brother, so I need anti seize on denso spark plugs ?? I heard it’s not required !! Any help would be appreciated

So in my opinion, a small amount is fine as long as you don't over torque the plug.
@@RodriguezRepairs Lexus dealer confirmed that I no need to apply any anti seize to the spark plugs, thanks anyway 👍🏼
Can i get a name and the size of the socket that you use to open that lug nut out?
Is that 1/4 or 3/8 do you have link to orders thank you very much
Ther is a comment up top were he responded your question
Dp you mind sharing What size do you need for the spark plug please
I want to order socket any help would be appreciated thank you !
Hey there, thanks for watching, the spark plug socket is 5/8or 16mm
Are the NGK plugs the one Lexus uses? Cuz these are like 25 bucks at o Reilly’s while the spark plugs at the dealership are like 15 bucks
Lexus use Denso.
Online Bell Lexus, $80 for a set of Denso. Free ship over $100 with "shiplexus" code until 5/31/21. Add a few oil filters or whatnot to hit $100.
Is it normal to have a little oil on the threads of the spark plugs?
that means that the spark plug valve cover seals are worn out which is letting oil seep through the threads. your valve cover gasket needs to be replaced
What’s the name of the electric tool you used to urn the bolts?
its called an Electric Ratchet
Ngk says to not put anti seize on their plugs
Yes i am aware, it is because it can alter the torque values in result, they can be over-torqued but as long as only a small amount is used, it should be fine. Also NGK has a special coating on the thread to help with corrosion
what's the name of the 10mm socket that fold ?
It's a swivel socket. A 1/4" will be easier to get under the plenum.
doe these plugs come pre gapped?
Yes most vehicle plugs are pre gapped unless its a vehicle from the 90s or below. I always verify the gap just incase the spark plug might have been dropped or mishandled in the delievery that it closed the gap from spec
Do does ngk come pre gap?
yes the plugs come pre gapped so you dont have to worry about calibrating them BUT sometimes the new plugs are dropped during shipment which can bend the ground electrode
