Description

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.

The graph above shows the results of installing the Heatshield gasket and bypassing the throttle body heating and idle control valve heating. If you examine a Type R intake manifold you will find that most sources of water heating are removed. Further temperature drops are possible when in addition the interior heating hose is blocked. What the graph shows, is that as you open the throttle, the intake temperature drops slowly as it cools the intake. When you descend a hill with the throttle closed or drive around town on a light throttle the temperature climbs quickly. It takes a good 15-20 seconds for the temperature to drop again when you open the throttle. So if you start your 1/4 mile drag with a hot intake manifold - you are only starting to develop maximum power near the end of the run when the intake has been cooled. The Heatshield gasket kit gives you 4-5% more power immediately by lowering the intake temperature.

Good product, a bit expensive

By Daniel Siebert on 10/20/2017

It's a thick piece of plastic for $40, it might net you 1-2 hp on a slightly cooler intake. Not gonna do you a ton of good unless you're using a CAI, forget about it if you're using a SRI with massive heat soak.

Cools the intake well

By Kevin on 5/29/2015

Before this mod my intake was burning up. I can now drive my car however long I want and even after all that driving I can go put my hand on the manifold and leave it there.

Good stuff

By jesus rendon on 4/5/2014

At first thought it was bs but I noticed the difference that the manifold didn't get hot as much worth it for the k24 and others
