Trick Flow 1" Phenolic Spacer for 1986-1995 5.0L Mustangs with a Trick Flow R-Series Intake Manifold.
Keep the air in your upper intake cooler and denser.
CNC-machined in the USA from premium phenolic material, Trick Flow® EFI heat spacers fit between the upper and lower intakes to create a heat flow barrier, keeping the air in the upper intake cooler and denser.
In addition, these heat spacers will allow the use of taller valve covers by raising the intake's height. Includes gaskets and longer mounting bolts.
