I've had K&N's on several vehicles, 2 of them were over 300K when I sold them. But I'm anal about maintaining them and I don't take shortcuts. I use foam filters when its really nasty conditions on my offroad toys.. __________________ Dave - PDX 1995 318ti - Active Black and Tan. 2005 330xi - Mtech 1 - 6spd - Orient Blue/Black |
