BBK 3/8-inch phenolic intake manifold spacer for 1986–1995 Mustang 5.0 applications designed for factory Ford 302/351W manifolds. CNC-machined from phenolic material, the spacer reduces heat transfer to the upper intake for cooler, denser incoming air and supports added timing advance with reduced detonation risk. It also raises intake height for additional valve-cover clearance and ships with gaskets, bolts and installation hardware.
