As some of you know, two of the front-running CRX's in the country were protested at this year's ARRC for running what are commonly known as cold-air intakes or CAI. As one of those two cars won the ITA race on the track but then lost the protest, the findings were appealed.

The CoA has just rendered their decisions....

I know that there has been a fair share of past debate about this in this very forum, but, it should now be clear that if/until there is a rules change, cold-air intakes for the 88-91 Civic/CRX (and by extension the 2nd-gen Integra) are not legal in Improved Touring.
