Does anyone have actual dyno results proving a particular cold air intake helps? I have a Kenne Belle s/c on my mustang and they sent me a 2 page email basically telling me that are the spawn of the devil and the gains are minimal.

 

Years ago we did dyno a bunch of intakes and filters. The gains were all 3-10hp depending on which one. So intakes do make power on R50, R53 MINI's.
