Owner reviews for air filter

The k&n cleaner has a lot of warning labels on it so I imagine it's a lot more powerful than soap and water. Plenty of dirty oil came out of mine when I cleaned it. I also rinsed mine with water and aired it out. Also need to re-oil the filter and let it dry in the sun and set in for ~ 12-24 hours to cure. Be careful on this step to not add too much oil.I plan on changing my K&N filter after ~3 years, just to be safe. I've had filters (from other brands) come apart on me in the past.

Well I'm glad I use Wix filters after seeing this test for my engine air and cabin air filter.

Project Farm has some really good reviews - and for most people, the Wix is the best daily driver. The K&N it seems letting in more particles may not be the hearsay and this does make a case for this being a legitimate concern.

Truly worried? Just use a simple (read: OE / OE supplier, like Mann or Mahle) dry paper filter.

Works like a charm I love it and highly recommend!

I installed K&N. Great replacement for the stock filter. Noticed a bit more induction whistle and the car definitely feels like it breathes better.

I put in a K&N filter and the improvement is noticable. I posted my milage on a filter post. The 300 mile trip includes a mountain pass and other steep elevation changes. We normally get 21-23 mpg, but we got 25.6 going, 24.2 returning at 65 mph average speed each way. I made the trip again yesterday and got 26.1 mpg going, average speed 69 mph. My last tank of gas for normal driving around town for 350 miles with a mixture of city and highway driving had a 23.0 mpg average. That is 1.5 mpg better than normal. I attribute this to improved airflow.

I'm pleased with my K&N as well. It was given to me by my stepson, who works at an auto parts store. Otherwise, I would have maybe gone for the dry filter. I really like the mileage improvement this has given me as well as the noticeable better response.

It's winter in Toronto and it's about -10 outside.. and i just put in a VR conversion... new Sparkplugs new wires new K&N Filter Neuspeed Chip Air Filter Oil just changed New G11 Coolant. anyway i keep checking the MFA and the oil temp is consistently in the 100-118 Celcius range.. during traffic or cruising around the streets its at 96-100 and when im going good on the Hiways at around 100-118

they let too much dirt pass through i wouldn't use them, especially on a turbocharged vehicle. the turbo will just suck all the oil out of them.

K&N gauze construction always worry me. Lots of pinholes for dirt to pass through. People clean them too often, so it doesn't filter well (they are designed to perform dirty).
