Hondata intake gaskets for the FN2/FD2 in stock. :cool:
£59.99 incl VAT



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.

Give us a call if you want one supplied with your GruppeM for optimum coolness.... of intake temperatures. :cool:

Sounds like a good idea. I can believe it works.
It does.

Get out your car after a drive and touch the manifold. It will be mad hot.
With a ptfe gasket fitted if you touch it its stone cold.

Basically a hot manifold pre-heats the intake air so all this money spent on good intakes is pretty much wasted.

Its supplied standard with all supercharger kits and we fit it to all our customers cars wanting to extract maximum potential from their setups.

Bit fiddly to fit but worth every penny.:D

What is the cost of the gasket inc fitting and how long would it take to fit.
Gasket is £59.99 and it's 2 hours to do the job which is £100 labour.

Remember in September 15% off labour as well so works out supplied and fitted this month only for £145.00 ;)

Most jobs you can DIY, but not everybody wants to take them on and are happy to let the pro's do it.
The AA still say their busiest time is Sunday afternoon/Monday morning after all the home mechanics can't get their cars running after trying things themselves though.:D

It`s easy to change the gasket yourself with the double nut method.
You don`t even have to remove the intake manifold.
Just peel out the OEM gasket with a pair of tweezers and slide the new gasket in. Sorted. Takes less than 45 minutes.

Do you see increase in bhp with this?

It's not about a BHP increase with these. It's about not losing BHP due to intake getting hot and therefore pushing hot air into the car. I know when I had an open cone filter on my EP3 I lost 8/9bhp because the air going into the engine was hot.

The colder the air, the more dense it is and more bhp you'll get. After all our cars love that cold early morning run huh?

I have had no issues with heat soak on my CTR with the piperx induction kit so not sur ei would benefit from this

Your missing the point. It has nothing to do with what intake you have. It stops heatsoak from teh head up the manifold which pre-heats the intake air temperature.

Rag your car around and stop. Open bonnet and touch the manifold. It will be hot.
Fit one of these and do the same and it will be stone cold.;)
