By all dyno charts, and I did not see one on the Mopar CAI that read the same as the others.
One site shows 10-15hp gained through the 5.7, one shows 18-21hp gained with the 6.1.
Only K&N shows dyno charts on the Challenger @ 32hp gained. It's ugly, and cheap looking, but at 100.00 less for 10+ HP more... I got the K&N
