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.

Love this little filter.

Reviewed By Thomas S (Greenville, TX) Reviewed for a 2015 Ford Focus —4/19/2016 5:39 AM

It makes my 2015 Focus SE sound like it has a lot my power than it does. At least now I know when I push the pedal to the floor!

Great filter

Reviewed By alexander k (JACKSON, TN) Reviewed for a 2013 Infiniti G37 —4/23/2016 9:23 PM

Filters fit great just like oem. Wanted performance filters without issue with oiling. These plus hps post maf tubes seem to add some performance. Noticed about 1 mpg more in the city.
