Product Details

Part Number: KTG-RBC-J35
Brand: K-Tuned

RBC/RRC intake manifold with J35 Throttle Body (Covers IACV Hole)
Make a little more power with K-Tuned Intake Manifold and Throttlebody Heatshield Gaskets. Our intake and throttle body heat shield gaskets are manufactured with a high grade temperature insulating plastic. They are precision cut and designed to replace the listed oem gaskets. By insulating the intake and throttle body from the engine heat, it will decrease the intake air temperature, and increase horsepower!
 
 So I guess you want to know how they work? The cylinder head gets quite hot when your engine is running. The purpose of these gaskets is to break the transfer of heat between the cylinder head and the intake manifold and throttlebody to create lower incoming air temps. As air heats up, it's density drops, reducing oxygen content, robbing you of power because your ecu has to compensate with less fuel. On average, you lose about 1% of density for every 5 degrees farenheit of increased temp! 
Heatsoak is a thing of the past when you get one of these installed on your motor. 
 
An added bonus is these gaskets are also re-usable. So you won't have to buy expensive oem Honda gaskets whenever you do some work on your car.

Fixed idle surge
Dylan Miles | October 26th, 2021
If you have a J35 and it idle surges, you need this exact gasket. I've tried the P2R one, and it didn't work. This is the real deal. I also got a cool whistle after install, similar to a throttle body spacer. Just get the standard shipping, it arrived in like 3 days. K series parts ships orders very fast after they are placed.
