CAI for SpecV

The archives are a wonderful thing...

air temperature was not the main benefit of the CAI. 2 minutes searching and
I found this post

Certainly lower air temp. is better for performance, but there's more to it
than just that.

this is the kind of stuff I like to see. It was a
great read. In theory, it would seem you have a good
and inexpensive design for cutting down quite
considerably alot of hot air coming in.
