I have a heatshield gasket on my EP3. It's a very good things. But the P2R use standard plastic i know. Hondata use phoneolic material and comptech use multilayer composit resin.

Plastic is not recommended.

 

Of course, plastic usually melts under heat, specially if the gasket is used under boosted application such as Turbo or Supercharge. But there are so many different plastic materials in the industry! If this aftermarket manufacturer is serious, they would not use ANY plastic, would they?

Are these gasket/spacer available for our Fit at Handata or Comptech yet? Do you have a link or prices?

 

I am not really familiar with the application of this type of gasket but I work with many resins and plastics and quite a number of plastics can hold up to heat pretty well. Teflon is used in cookware, we all know that but often we forget. Many resins and some composites become brittle
and or burn under certain temps or just degrade and loose thier ability to
conform to the desired area or warp.

What are the temps for that exchange area? (I did get a kick out of the
how long I could hold my hand there...hahahaa)

 

I finally bucked up and ordered one. Either way if it works or not i think its worth a try. Maybe down the road it will come in handy with other mods i do. It cant hurt to try and its not like its gonna hurt the motor or anything.

 

Got the gasket today from K20tuned. Very nice!! I cant wait to instal it. Thanks again for the write up Fit of Rage.

 

just PM me if you need any help!

 

did anyone experience any check engine light? being forgetful, i forgot to plug the air sensor behind the intake, i took my intake box out to make more room, i then realize i forgot to plug it back in so i turn off engine and plug it back in, but the light is still on.

 

I have a very hard time believing that this will actually do anything. The air in the intake manifold is not sitting there getting heat soaked its being sucked through. I really doubt the manifold gets so hot that its heating the air passing through it quick enough to result in a power lose.

And to the dude talking about his intercooler temps dropping from the plastic gasket.... thats not even logical. The intake manifold is the last thing the air travels through before going into the head/engine. How hot intake manifold gets will not affect the temp of the intercooler, the air has already gone through the intercooler by the time it reaches the manifold. Its not possible for intercooler temps to drop by 38* because of a plastic gasket on the intake manifold. (I think thats what you were trying to say, your post was all over the place)

 

IT didn't do anything. If it did, it's completely un-noticeable. It's pretty much useless.

 

Darkstars shut the hell up DUDE....

Dont start attacking another member on hear.....

what was said is " it will have no effect on the honda fit motor".... and im sorry if my reply was all over the place.....i would hate to confuse you


Hondata Intake manifold HEATSHIELD gasket for 2004 Dodge SRT-4 .

The Heat shield is a replacement intake manifold gasket made from special high temperature plastic, designed to insulate the intake manifold from the cylinder head.

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 74 degrees fahrenheit. " Its not possible for intercooler temps to drop by 38"

Fact: For every 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.

Hondata used data logging software to measure intake air temperature under varied driving conditions on a test vehicle with this heat shield installed.

Around town, testing has shown an average drop of around 15 degrees F 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 45 degrees F drop has been measured.
The results of installing 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 Heat shield gasket kit gives you 4-5% more power immediately by lowering the intake temperature.

 

Oh come on its not all that worthless. Look on the bright side it was under $40 haha. Im gonna send my intake manifold to jet hot and have them coat it and see if that does anything on top of the gasket. Im gonna get it in bright silver so atleast it will make the engine bay a little bit more exciting if nothing else. I would do red but that may be too much. Havent decided yet.

 

there is plastic all over the engine bay and doesnt melt..what bout the idea of putting "socks"/cloth under the hood...
i am sure the slight drop in temp that the plastic plenum provides does make some diff...it si not gonna be huge no but maybe very slight diff...

 

My bad I didn't realize not agreeing with someone is attacking them... good call there.

I still don't believe any of what you posted. I still don't believe that the intake is gonna get so hot its gonna heat up th intake manifold, the throttle body, all way back through a few couplers and charge pipes and then heat sit there and soaks the intercooler.

Plus you said it can heat up the air to up to 74* but then in testing the most was 45* your story about how awesome it is doesn't even match with the story about the testing.

 

anyone know when the hondata gasket will be out???

 

I got passwords gasket too, installed last week. [=

 

The way this the gasket was described to me when i had my 05 RSX-S was that it makes the car run similarly to when the car has just been started and the engine temps have not risen yet (that slightly more pull that you feel when you've just started your car in the mornings... probably because its a bit cooler). Of course i doubt anyone will really be able to feel the difference with it on or off but i'm sure it does give you some minimal performance and if its under $40 i can see why people would try it. Kinda like those people that remove the rear head rests for "weight reduction", every little bit helps? right?

 

Thats more or less what i thought so thats why i ordered it. Yes its only a small gain but its a gain none the less and depending on what else i do down the road it may help out even more.

 

great mod, but please be patient and dont loose any bolts and do it right!

 

Can someone who has a manual please post the torque specs so they can be added to this thread. Tightening bolts in to aluminum can be very deceiving and the last thing you want to do is shear a bolt off or ruin the threads in the head.


Anyone know where to get the online version (free) pdf of the shop manual?

 

something like 20 foot pounds will be more then sufficient...

As for the mod, i think that polishing the inside may give more gains... it's only a portion of the intake that get's heated by the head, not an entire manifold with coolant passing thru...

Marko!!
