Hondata have developed a special high temperature insulating gasket which replaces the stock intake gasket. This and bypassing several heat sources significantly reduces the transfer of heat from the head to the intake and incoming air giving you up to 5% more power.
Turbocharged cars often use an aluminum intercooler to cool the air compressed by the turbo. The intake manifold is also made of aluminum but because it is heated by the head from combustion and coolant, works in reverse to an intercooler by heating the intake air by as much as 50 C.
Fact: For every 3.3 C (5 F) rise in intake temperature, air density drops 1%. The hotter the air, the less fuel the computer injects to compensate for reduced oxygen. HondaLogger datalogging software has enabled us to measure intake air temperature under varied driving conditions.
Around town, testing has shown an average drop of around 10 degrees C which is good for around 3 percent power increase. Remember though that 3 percent power increase is difficult to feel. You'd feel a greater change in performance getting rid of that passenger. In certain conditions a 30 C drop has been measured.
The Honda manifold is heated in up to 5 places. From the head, the interior heating takeoff hose, the cold idle valve, the idle control valve and the throttle body heater. The Heatshield gasket kit contains an insulating gasket, and installation instructions. A race version only version with the thermostat bypass blocked is also available.
Fitted perfectly on my 03 JDM CL9. Didn't feel any improvement in performance but the intake manifold can be touched with bare hand after driving so basically its doing what its supposed to do by isolating the engine block to transmit heat to the intake manifold (Body to Body).

worked just like it was supposed to, tough install. very small power gains on the dyno as expected. the part does fit and does not look like the above picture so dont worry about it looking wrong.

Works as expected, no jokes! The intake manifold feels much cooler when it's mounted with this gasket. Handwarm instead of heat soaked.

Product is flawless it really works, intake manifold is now hand warm after 2 hours off full abuse on my impreza STI . A cheap and reliable way to improve performance. It also fits like a glove.

As promised, the gasket does indeed keep manifold temps cooler! Especially nice given that I'm using a non-intercooled S/C. Well worth the money.

Product is great . Small gain in power . cooler intake temps. I recommend that the nuts be checked after 20 miles and then again after 50-100 miles to make sure they are tight. Great product.
