Great news, these Spacer Plates now fit all modern Gen 3 Hemi Heads, 5.7L, 6.1L, 6.2L and 6.4L. Non-Hellcat models will need to drill spacer plate for Oil Fill and PCV.
After first seeing a Hellcat 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 engines 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 FI went and made 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 the factory gasket
- Help reduce oil blow by
- Deliver all of the boosted air into combustion
- Reduce crank case pressure
- Gain HP/TQ
Includes:
- Longer grade 12.9 bolts for Hellcat models only (HHP Racing Exclusive!)
- Blower Spacer Plates with O-Rings installed
- Thermal Blanket
5.7L, 6.1L and 6.4L applications will need to source 10mm longer bolts than what you currently use due to variations in engine and intake manifold combinations.
