One part that customers arent familiar with, and is frequently overlooked in a car buildup, is the Hondata intake manifold heatshield gasket. We carry it for the 95-99 Dodge Neon Dohc engine, and for the 03-05 SRT-4.
Here we have a photo showing the Hondata gasket on top, and the factory 03-05 SRT4 gasket on the bottom.
As you can see in the photo above, the gaskets are identical in size. The difference, is in the material, and thickness of the gaskets.
The factory 95-99 Dodge Neon Dohc and 03-05 Dodge SRT4 both have aluminum intake manifolds that absorb a LOT of heat from the engine cylinder heads, therefore heating up the incoming air into the head. This can make a difference in as much as 3-4% of your cars horsepower, because the hotter the incoming air, the less timing, boost pressures your pcm will allow into the engine.
Sound like hogwash ? Well, think back to a day where it was cool, say 60-70 degrees outside with low humidity, and think about how great your car ran that day. Next, think about how your car ran at 90-100 degrees. Theres a NOTICEABLE difference in power! Thats because the pcm makes adjustments based on the incoming air temperature, so if you have a way to keep your incoming air cooler, then youll make more power !
The Hondata gasket keeps the air cooler, by using plastic (great insulator) thats 3 times thicker than the factory intake manifold gasket which is made out of a paper type material.
The gasket material is thick enough to help insulate from heat, HOWEVER, its not too thick where you wont be able to reuse your factory bolts! You can use the same factory bolts, and it will seal just as well, if not better the intake manifold to the head. We have had cars with 25+ psi of boost that have not had any leaks with the Hondata!
