Trick Flow 1" Phenolic Spacer Kit for 1986-1995 5.0 Liter Mustangs using a Holley Systemax EFI Intake Manifold.
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 new gaskets and longer mounting bolts.
*A taller hood may be required for clearance to the intake manifold.
