Now suits all modern Hemi Heads, 5.7L, 6.1L, 6.2L and 6.4L
After first seeing a Hellcat/Trackhawk in person we saw the IAT sensor location issue and figured we’d apply the same tech that we do to the other cars we make parts for.
So let’s isolate the blower from the engine, let’s get that IAT sensor to read true and let’s also get the blower to run at a colder temperature.
During R&D we were shocked to find that the cylinder head on the Hellcat/Trackhawk carried over from the NA engine with the oil fill port on the mating face of the head!
And then even more shocked to see how they have attempted to seal this area with the factory gasket (see video).
So we went about making a double sided o-ring Spacer plate to not only make your intake temps colder but to also help fix the oil blow by issues you are suffering from
✅Lower intake temps
✅Lower blower running temperature
✅Better resolution of IAT sensor
✅Eliminates factory gasket
✅Help reduce oil blow by
✅Fixes factory leaking intake gaskets
Package includes: Blower Plates, thermal blanket, install pins (bolts are not included as there is so much aftermarket variation, you will need to source 10mm longer bolts than what you currently use, we recommend Belmetric for your US bolt supplies).

Custom made o-rings on both sides of the plates as well as the oil gallery to help with blow by issues
