Multiple Choice

The intercooler allows you to run more ignition timing.

Explanation:
Ignition timing is limited by the tendency of the mixture to knock (detonate) in the cylinder. An intercooler cools the air after it’s been compressed by the turbo or supercharger, which makes the charge denser and significantly reduces the likelihood of knock. With cooler, denser air, you can advance the spark more (ignite earlier in the compression stroke) without causing detonation. That additional advance translates to more power, especially under boost. Without the intercooler, the hotter, less dense charge increases knock risk, so timing has to be kept more retarded. Therefore, the intercooler enables more ignition timing.
