yea im interested.. the ony ting is i heard -1+2 is the wayto go... but then on here ive seen so many people said theres not too much of a noticable difference... plus you rev wayyyyy higher on the highways... is this all true?
On my 05 600, when I switched to a K&N I lost a noticeable amount of midrange. I might have gained 1/2 hp at the very top, but I couldn't feel any difference up there. I had about 8,000 miles on it when I made the switch, so I knew what it was supposed to feel like. I ordered a stock filter three days later and got my midrange back.
There are other aftermakret filters which may work better, but for me, a stock filter was best.
