Phenolic Intake Manifold Spacer Set

Our Industries unveils a truly needed product to the demanding enthusiasts in the Mazda community. The flimsy OE intake manifold gasket which leaves Mazdaspeeders questioning whether it assures a quality seal is one issue, but the heat transfer between head and the intake manifold is another issue all in itself.

By limiting the heat-transfer between the two components utilizing a 3/8" Thick Phenolic Spacer (known for excellent thermal properties at a competitive price), intake manifold temperatures decrease dramatically, allowing for the incoming, pressurized air to stay cool, thus reducing knock issues and creating more power. Also includes the spacer for use between the throttle body and intake manifold!
