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.

2014 Focus SE

Reviewed By cornelio u (Mesa, AZ) Reviewed for a 2014 Ford Focus —9/12/2016 9:26 PM

Got the green filter in hopes of getting better Gass millage not for power as most do,i drive 70 miles round trip to work. I also modified my airbox by cutting 2/3rds of it and made an intake similar to the FS works for $100 bucks less. The green filter looks to be well made, on par with any K&N I have ever bought.The intake sound is much louder now vs stock, but in a nice deep way. Mpg test not done yet. Well see.

AFE Filter Is the best

Reviewed By Steven H (BUCKEYE, AZ) Reviewed for a 2016 Toyota Camry —9/21/2016 10:45 AM

I have had this in my 2016 Toyota Camry for about 3 weeks I did a trip to California from Arizona and notice an impressive 33 MPG. I typically average 26 in everyday driving and I have been averaging 28- 29 lately. Filter will definitely pay off in the long run. I will recommend this to anyone, if your looking at K&N don't, I have had them before and decided to change it up and I have zero regrets from it.
