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.

'16 Focus St

Reviewed By Charles D (AUBURN, IN) Reviewed for a 2016 Ford Focus —3/8/2017 7:36 AM

Easy to install. Fix is spot on. I like that the end is open for more air. Seat of pants more power.

True improvement for high altitude

Reviewed By Joshua L (Leadville, CO) Reviewed for a 2016 Jeep Cherokee —3/20/2017 11:45 PM

At 10200 ft, the KL was in need of better air flow. The AFE supplied a quicker response to rpm climb a little extra growl and 3.5 mpg more than I was getting before with same aggressive driving. For the price you can't lose.
