I just joined the site and was wondering if anyone has put the new K&N cold air intake on there charger yet K&N has a dino read out of before and after and it took a magnum R/T from 290 at the wheels to 310. They are saying it will work on any of the new 5.7's and the 6.1's 20 more at the wheels sounds great and at only 259$ or something around there seems to good to be true is it?
