    I am new to the area, and I just picked up a K&N filter for my WRX. I was recently informed that the K&N can cause problems with my mass air flow sensor because of how dusty NM is. Has anyone experienced this or a similar problem from using a K&N out here?

    Thanks!

    Well, K&N has always claimed "the dirtier it is, the better it works!" for their filters...
    Never heard of the problem, but you could buy one of the pre-filters K&N makes that are designed for high dust situations (usually off-road/Baja stuff).
    Finally, glad to see a post in this area of the board!!! Is Rocky Mountain Division the most boring or what? Must be, judging from lack of posts.

    Your WRX uses a MAP (Manifold Air Pressure) sensor, and not the problematic hot-film (dang, wire? Either way, the '99 was the bad year.) sensor of the '99 model 2.5RS.

    You shouldn't have any problems at all with your K&N filter.

    For WRX-specific questions, check out the forums on the i-Club ([url="http://www.i-club.com"]www.i-club.com/forums[/URL])

    There was a big discussion of K&N filters on the E36 M3 digest some time ago.

    Nothing was ever really resolved, but one of the foremost tuners is not a K&N fan, based on some tests which showed K&N to be less effective at small particle filtering. He uses ITG filters on his highly acclaimed intake kits.

    The ITG filters are oiled foam filters.

    Check them out at [url="http://www.itgairfilters.com/"]http://www.itgairfilters.com/[/URL]

    I have one on my M3 and am quite happy. Have used K&N in the past.

    No strong feelings one way or the other, but the ITG is certainly one of the best available.

    I've tried both K&N and ITG. I really like the ITG much better than the K&N. The fit in the airbox is superior. The oiled foam design is easy to maintain. After a recent rallycross a little vacuuming put it back in inspection order.
