yeah thanks guys. I fully understand about the re-sale value. Forget K&N, Im talking about something from mopar. I read something not too long ago that was tested on the Hemi 5.7's like in my Ram that promised or advertised 10% horsepower increase on a cold-air intake and on the chip from MOPAR. So on a 345hp engine if you just did those two things wouldn't you end up with about 400hp at least? These were MOPAR products tested for the Hemi.
