VW Touareg

Reviewed By Peter H (Santa Maria, CA) Reviewed for a 2004 Ford Focus —9/5/2007 9:36 PM

I put the filter in with some sealing grease; it fit in nicely. It's only been 40 miles; so far I may be getting a tad bit better mileage, maybe 2 or 3%. The Touareg is heavy and slow with a V6, so I don't know if hp increase will be too evident.

Air Filter

Perfect fit still haven't determined fuel savings. Whats great is I never have to replace just wash, dry, and re-install no need for oiling.
