"I've been putting K&N Air Filters in all of my vehicles since 2002. They filter pretty well and allow the engine to breathe a little better. If you live in a very dusty environment or do a bunch of off road driving, you may want to stick with a stock filter. The only thing you have to watch for is servicing the filter. Don't over oil the filter or the oil will collect on the mass air sensor and create some problems. Other than that I think the small risks is worth the reward of more power and fuel mileage." —Richard O from Williamsburg, VA bought a K&N Air Filters for a 2009 Toyota Sienna.
