Make a little more power with Exile AutoWorX Intake Manifold Gaskets. Our intake gaskets are manufactured with a high grade PTFE. They are precision cut and designed to replace the listed oem gaskets. By insulating the intake from the engine heat, it will decrease the intake air temperature, and increase horsepower! So I guess you want to know how they work? The cylinder head gets quite hot when your engine is running. The purpose of these gaskets is to break the transfer of heat between the cylinder head and the intake manifold to create lower incoming air temps. As air heats up, it’s density drops, reducing oxygen content, robbing you of power because your ecu has to compensate with less fuel. On average, you lose about 1% of density for every 5 degrees farenheit of increased temp! Heatsoak is a thing of the past when you get one of these installed on your motor. An added bonus is these gaskets are also re-usable. So you won’t have to buy expensive oem gaskets whenever you do some work on your car.
