4.0 out of 5 stars Filter works for me, October 2, 2007

This review is from: K&N 33-2144 High Performance Replacement Air Filter (Misc.)

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.

K&N makes a great product after changing out the factory filter I am getting about 1 to 1.5 MPG better with my truck now. Be sure to purchase the cleaning kit also

Tried one of these Air Filter in a 2005 Toyota Tundra. I noticed a quicker response on the Gas pedal. It was something I wanted to try for a long time. Glad I did.
