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.

Better MPG

Reviewed By Jeffery C (FIFE, WA) Reviewed for a 2015 Ford Focus —5/30/2016 8:28 PM

I've seen about a 7% increase in mpg. The filter is well made. There is a bit more growl because the end is now open. The sound is mostly noticeable during hard acceleration. I have the 2.0 with DCT.
