Air filter K&N or UGREEN

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.

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.

K&N filters are reusable. Totally worth the upfront cost.

I just did the switch to a K&N filter recently on mine. Did not notice any difference. I remember feeling a greater difference in my VR6. Maybe its the fact one is N/A and the other F/I.

I found a used ABD racing filter and I could feel it with out a doubt. I bought a K&N filter and drilled holes in my box and I say it was a waste.

Over cleaning a K&N does more harm than good. K&N's need dirt to be effective. Clean K&N's let through too much dirt, until they become effective.

I'm not a believer in K&N. I've always thought of it as being rather gimmicky.
