The MR. GASKET Phenolic Spacer Quad 4-Hole is a 1-inch thick intake manifold spacer designed specifically for small-block engines that require thermal isolation between the carburetor and intake manifold. This spacer is ideal for those looking to enhance engine performance in street engines, weekend cruisers, or performance setups.
Constructed from phenolic composite material, this spacer effectively reduces underhood heat transfer, thereby lowering incoming air temperatures and improving fuel atomization and combustion efficiency. The phenolic material is approximately 100 times less conductive than aluminum, making it a superior choice for intake spacers in carburetor applications.
This spacer is particularly beneficial for vintage small-block Chevrolet, Ford, and Mopar engines with four-hole carburetor flanges. It is especially effective for street-driven vehicles where underhood temperatures can significantly impact performance, providing measurable gains in throttle response and driveability.
