Sorry for the delay.. been out of town (work sent me to la... yay!! You know there are no ugly girls in LA?

But anyway.. My stockl 2k 4x4 does 67 up the back of kirker pass (big hill behind concord pavilion), with the K&N... 68.. A little dissapointing.. a word of caution.. This is VERY loud.. Like 2 to 3 times stock... although i did notice it stayed in 3rd more of the time, only dropped into second once, where stock went 3 times..
