This 1" thick spacer for standard GT40, Also Explorer and Cobra 5.0 intakes. Has the effect of making the runners longer for more torque, Raises the upper intake for more valve cover clearance and helps insulate the upper manifold from heat that really hurts the power on any engine. Alloy CNC machined Instead of Plastic composite material.
Beware of the cheap cast black plastic imported spacers the holes don't line up do to mold design and shrinkage also the material is not suitable for automotive use. Just use the correct hardware, It could fit for Explorer & Cobra intake as well.
