Build A Faster Car - helping drivers engineer

The MAF and IAT (Intake Air Temp) sensors sit in the incoming air stream, translating airflow into little 0's and 1's the PCM can use to figure out the amount of necessary fuel to add for proper combustion. Over time these sensors can accumulate dirt, as no air filter stops 100% of incoming silicon particles.

This article is to address the lack of and confusion of information on this forum about intercoolers. Since I've also made this mistake myself (I once posted a silly thread about the speed6/speed3's intercooler being "tiny") I feel I'd like to share what I've learned with the community. This is merely a combination of information retrieved from the internet, personal conversations with shop/shop owners, road course guys, and a few books.
