Title: Filter works for me
Review: Toyota mechanics will often tell you the filter will foul the MAP sensor because the company insists they do. If you put too much oil on the filter, it can foul it (there are ways to clean the sensor, but off hand I can't remember them). After cleaning the KN filter after 20,000 or so miles, many people spray too much oil on it and that will foul the sensor. Follow KN's re-oiling instrictions religiously. I have used a KN filter on an '06 4Runner for almost 40,000 miles without a problem and got a little better gas mileage. One Toyota mechanic admitted to me that they are supposed to tell people not to use them, but he'd rather be honest.
Is the review positive or negative?
