It seems pretty legit. It just allows for lower intake temps. The gasket coupled w the other mods they do to lower temps make for a nice gain in HP.

Not sure if I felt any difference but the results are on paper. Also it is a pretty straight forward install. No need to drain coolant for the intake manifold gasket.

The hardest part is getting the bolt from the IM located UNDER the IM.

Ordered one recently, no reason not to. It works on paper across the aftermarket, my WRX will get one. Can't hurt.

Are people putting intake mani gaskets on both sides of the hondata gasket?

i really don't see how just this gasket can you give such change... maybe its true, i don't know but most of my mechanic/tuner friends just laugh at me.
i've contemplated this many times...
Temperature plays a huge role. I don't think this increases HP, rather sustains HP with increasing temp from the engine.

If you look up dyno testing, you'll see that results with lower temperature yields higher HP output.

yes def. cYn i can understand that... but are the drops in temp really being seen from this gasket or rather from the TB coolant bypass?

Also, its recommended to also install the P2R gaskets as well right? anyone done this?

I know HONDATA is reputable but this idea just miffs me a bit... i can understand heat transfer, heat soak , etc and just knowing how hot our ambient temp. in the engine bay is... i don't see how this gasket will overcome that... yes maybe it will help in direct heat transfer ... but don't see how it will combat all the other heat producing factors

i guess similar arguments have been made to those wrapping their air intakes and making insulted boxes, etc.

don't know if its worth the $100 for all the gaskets... but i guess every little thing could help


Economy improved?

^ I can definitely understand the skepticism. I was just like you but the enthusiast inside me overcame that. I have both the IM and injector gasket. Injector gasket is a bitch to install.

i have both the hondata intake manifold gasket and the p2r gasket. The hondata gasket goes between the block and the intake manifold, while the p2r goes between the injector base and the intake manifold (please correct me if i'm wrong, it's been awhile).

I guess you can think of it like this. Think of a boiling teapot. Would you rather put your hand close (not touching) to the pot itself or touch the actual pot. I see what you mean by "whats the point, its hot up in there anyway", but I think the actual physical transfer of heat is more significant than the ambient transfer of heat.

No matter what in traffic your going to see IATs rise, heatsoak happens. But at 15mph or more I saw a huge difference in IAT temp between the gasket and no gasket.

At this point I usually run about 5 degrees warmer IATs than the outside temp (cold air intake). Theres also a huge issue with the RBB mani, it sits directly behind the rad soaking up heat. With and RBC or RRC heat soak from the rad is not as prevalent.

Do you feel it, no. But lets say you race someone and your dead even every time. You do the coolant bypass, and all the gaskets. It might get you 5-10hp, well that small gain would most likely let you pull on that car.

Its a cheap mod and gets your a few HP its worth it in my book!

I highly doubt you are going to see 8WHP with the insulating intake manifold gasket. I suspect that was a fluke on the dyno with the hood up.

Coolant definitely has to be drained when installing the insulating gasket between the head & the IM.
There is a coolant passage there. It's a terrible desigin IMO.
Even with the insulating gasket, hot coolant is still flowing through the corner of the IM heating things up.
This means that even with an insulating gasket in there, the coolant is still heating up the IM.

It is possible to eliminate the coolant flow thru the IM but it's not easy since the Idle air bypass sensor is in there.
JTso has detailed info & pics on the Acura zine forums.
It would be easier if one just eliminated the Idle air bypass valve but not sure if you want to do that for a daily driver that sees wintertime use.

Don't forget that the throttle body coolant bypass has to be done also to get rid of that heat source.


IMO, installing bypassing the throttle body coolant & then installing the P2R insulating gasket between the 2 halves of the IM is the best bang for buck. Super cheap & easy install.

P2R Thermal Intake Manifold Gasket (between manifold and inj base), 04-08 CL9 TSX & 03-07 CM Accord, P103 - HeelToe Automotive

I've had this set up with zero issues for over 2 years now. The top half of the IM is nice & cool after a drive.
But I didn't gain 8WHP!!

anyone that has ever been in 95-97* with 50-70% humidity in florida knows what heat soak really is. If this product can lower IAT temps 40* like i have seen it do, im sure it will help alot in this...its not going to increase hp its going to sustain what you have at higher temperatures.

I wouldnt say whp thats why i wrote hp but there are still some gains.

Secondly if you not live in a very very cold climate it is ok to run without a IABV. Ive been running without one for a good amount of time without any issues.

Actually, the only issue I had with installation of the IMG was coolant leaking out.... It helps to drain your coolant if you have not done it at all..

Hmm so the p2r and the hondata are 2 diff gaskets?
Yes, I have them both. Just make sure you order the P2R IMG between the Manifold and Injector Base..
