This 1/2" thick spacer for standard 5.0 intakes. Has the effect of making the runners longer for more torque. Also raises the upper intake for more valve cover clearance. The best part is it helps insulate the upper manifold from heat that really hurts the power on 5.0 Mustangs, and Thunderbirds. CNC machined from a Automotive approved heat resistant. high tech composite material. This material is not cheap but much better quality.

Includes 1/2" SPACER

Bolts, Studs, washers, and nuts as pictured
