Technical Details
When it comes to engine performance, hot air is the enemy. These phenolic spacers do an excellent job of reducing heat soak in the intake manifold by removing the metal-to-metal contact between the manifold and head. Thus, leading to reduced intake air temperatures and denser air. An additional benefit is that cooler air has a higher resistance to knock, allowing more ignition timing advance - or boost. Either way, they both equal more power!
