Phenolic Spacer Question

[Pushit2.0]

your intake manifold and head are huge heat sinks for the engine to disipate heat threw. Now the air traveling threw your IC piping and intake manifold takes heat from the piping and manifold, there for being hotter then it needs to be, so if the manifold is colder, there will be less heat transfer. Which will provide a cooler more dense air charge which = more power.
