          Comments about K&N Replacement Air Filter:

          My truck just feels like it breathes better. From initial take off just smooth acceleration, small unnoticable improvement in gas mileage. something like .5 mpg more. If you want power get a CAI but for drop in k&n is really good. especiallly since I got a $20 off coupon and picked it up for [$] instead of [$].
