Spacers are specific to the hellcat based heads and will work with any blower type, the only difference between these plates and the modern hemi plates is “the hellcat specific bolts” if you have an aftermarket blower eg whipple or magnuson order the modern hemi spacers and source your own bolts)

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.

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
