Intake Manifold Plenum Spacers

Trick Flow® EFI Heat Spacer Kits

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. This keeps the air in the upper intake cooler and denser. In addition, they will allow the use of taller valve covers by raising the height of the upper intake manifold. The EFI heat spacers are available in 3/8 in. and 1 in. thick versions; gaskets and longer mounting bolts are also included.
