We have seen up to 40% increase in intake manifold temperatures without the use of a thermal gasket.
Here is a useful 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.
Our main goal in redesigning these gaskets is that we have been purchasing them from many different vendors for the past few years. Until now we have not been satisfied with the material that these gaskets are made from. Problems that we have seen with lesser quality materials are: melting, poor fitment, and worst of all shrinking to block the intake port causing a loss in power. Feel confident that our gaskets are the best on the market in quality and value.
All of our turbo manifolds maintain a 10 year warranty to the original owner from the purchasing date. Our warranty covers all material and manufacturing defects. All of our fabrication is done in house in the USA. We utilize the best material and fabricator available to ensure that you'll never have a problem. We do NOT cover warranty claims on issues caused by you. We also do not warranty second hand owners at this time.
