I just purchased my first Jeep, and it's a 2012 Grand Cherokee. I was wondering if anyone knew anyways to add mpg and hp like K&N air filters, cold air intakes etc.????
Not a fan of K&N or any kind like them. Just use a good paper element like a Wix or Purolater. The claims of whatever they say 3-5 hp or something is ridiculous and not worth it.I would just look into a good free flowing Cat back exhaust with mandrel bent pipes a kit like a Walker or Gibson.
