We install a complete RR racing intake kit in our 2016 Lexus GS-F!!

If you drive a Lexus F car, the RR racing intake setup is a MUST. Retains factory MAF housing, shields the intake from hot air, and deletes the crank case breathers from the intake tube!

Good vid. I did the RR racing heat shield and did the Tom's carbon intake tube to keep the factory look.

[@SEsGarage]

I couldn’t justify the $600 price tag for an intake tube. I definitely gave the Tom’s a hard look though

[@nemesisl4240]

@SEsGarage yeah I was lucky to get mines at half price.

Great video.

Great video, thanks for sharing. I've got an IS 500 and am about to do the intake similar to what you did here.
Can you give some advice on the cold air intake box?
Is there a benefit to modifying the box so the flap stays open the entire time, not just above 3500 rpm? Would there be a detriment? I read a comment elsewhere saying keeping it open worsens low-down torque, but no explanation how was given.
If one were to keep the intake constantly open, how can they do that while preventing a vacuum leak? Keeping it open is as simple as removing that small hose, but is that safe, or should a further step be somehow sealing up the two solenoids?
Thanks for your perspective, just curious, I probably will leave the flap connected anyway.

[@SEsGarage]

So the way that flap works is when the car supplies it vacuum it’s closed closed and then when you remove vacuum, it opens. Your best bet would be to just unplug that vacuum hose and follow it back to the solenoid and put a vacuum cap on it

[@user-qv9eo5jp5x]

You are the best, thanks for responding!

[@SEsGarage]

@@user-qv9eo5jp5x your only negative I could see is the fact that when that flap opens, it’s drawing in hotter air from the engine bay rather than air from the front bumper. If you add the RR racing heat shield that should negate most of that though. I personally like the sound of the crossover when the flap opens so I plan to leave mine alone

[@ap50]

Hey man, would u recommend this recommend having it for some time now? Is it worth it or just a gimmick?

[@SEsGarage]

I like it solely for the way it looks when I open my hood hahaha. I don’t recall any performance gains but it sure looks cool

[@accord1224]

Wonder why RR Racing removed the 2 crankcase ports on top of the air intake elbow. Based on your explanation in your video their intake design could trigger some lean codes.
I also could not justify the Over priced Toms Cold Air Intake so just bought yesterday the RR Racing Cold Air Intake with Heat Shield. In my opinion all you need is the Heat Shield for the Small Performance Increase but bought the whole kit primarily for looks since such a small performance gain.

[@SEsGarage]

I had concerns with lean codes as well and brought them up to their attention! Technically opening the breather hoses to atmosphere is allowing unmetered air into the engine when that PCV valve opens. They assured me they’ve been running this kit and similar on the ISF for years with no issues. For what it’s worth, I plugged in my scanner and drove the car while monitoring short term and long-term trims and they stayed within a reasonable margin. +-10% give or take. And I haven’t had any lean codes as of yet. It’s definitely something I’m keeping an eye on

[@accord1224]

I guess the question now since you had this setup for a while is any issues or check engine lights related to this Cold Air Intake Mod?

[@lexusrcf2441]

The RR intake kit silence the high factory Yamaha doe shuts. It suxxx I took mines off and reinstall my factory intake which is better

[@SEsGarage]

I can still clearly hear the intake bypass open up around 3500. Are you sure you extended the vacuum lines correctly?

[@tamekaxlovely]

Dude that is awesome! I want to do this to my IS F so bad but it costs like 10k & I’m too poor for that 😂
How much it cost you? Any dyno #’s?

[@SEsGarage]

This is just the intake kit! I wish it was their supercharger😂

[@NiceGuyCurry]

I just installed the RR-Racing intake with a Tom's high flow filter and the heat shield. In normal driving mode, do you still hear your secondary intake open up around 3500rpm or does installing this eliminates that sound?

[@SEsGarage]

Yes I can still hear it clearly

[@NiceGuyCurry]

@@SEsGarage I am trying to figure out why I'm not hearing mine

[@SEsGarage]

@@NiceGuyCurry check your vacuum tubes and nipples on the solenoid and under the heat-shield. Failsafe is in the open position so worse case it’ll be open all the time. It applies vacuum when it wants it closed and removes vacuum when it wants it open

[@NiceGuyCurry]

@@SEsGarage I will check it once I get home. Am I checking if the hoses are connected to the ripples on the solenoid and down by the intake box? May I ask how can I check to see if the solenoid is working itself?

[@NiceGuyCurry]

I figured out what the issue was. I had the vacuum hoses on the solenoid on wrong which was preventing the flap from opening at all. She is all set and good to go now and thank you for your help and support and responses.

[@mytube2415]

Can you install a throttle body spacer on this engine

[@SEsGarage]

If they made one, I wouldn’t. They don’t provide any performance gains
