Trick Flow® EFI heat spacer kits help you fit your spacer between the upper and lower intakes to create a heat flow barrier. That keeps the air in the upper intake cooler and denser. Plus, these CNC-machined phenolic spacers provide clearance for taller valve covers. They're available in 3/8 in. and 1 in. thick versions and include gaskets and longer mounting bolts.
