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.

very good filter

Reviewed By Jerome D M (Prescott, AZ) Reviewed for a 2016 Jeep Cherokee —4/25/2017 10:39 AM

It fits perfect and there was an immediate seat in the pants change. Leaving my home I have to go straight up hill and the Jeep now pulls better than it ever did. Not saying it was a huge difference but noticeable the Jeep shifts sooner and my gas mileage has went up slightly. So don't expect a huge horse power gain but it did make a difference in torque by my seat in the pants test. Well worth the price. The filter media does not cover the entire hope they change the design to fix this.
