We designed many types of RAM-Air Design CAI Intake Set-ups, all of which worked really well at high speeds and Full Throttle, but had some major flaws with part throttle due to MAF meter implications.
We divised our
Type-S CAI System to be the
Very Best Available Intake Upgrade for Ecotec and Supercharged V6's without any negative side-effects. Cost is $295 and Dyno Proven Gains from 4-9kW are expected.

Hope this helps.
