There is a noticeable smoother run for my old 04 Rav4. The first one I used was great . I went to a quick oil change place, they used some house brand. There was a noticeable change in how the engine sounded and even idles. Just did my own change back to K&N, smooth and quiet idle and running .

I would highly recommend using K&N oil filters.  I started using synthetic oil in my 2008 Toyota Matrix and changed the oil every 5,000 miles.  At first I was using stock oil filters on the car but began noticing that around 4,000 miles after the oil change the cars horse power would significantly drop and on cold days the car would run ruff.  I changed out the stock filter for a K&N and as soon as I took it out of the box and compared it to the Toyota oil filter, I knew the K&N product was a much better filter.  Since I have been using K&N my cars horse power does not drop off after 4,000 miles and ruff starts and performance on cold days is no longer a problem.  I can usually pick these up for about $15.00 and they are well worth the money.  I'm confident that synthetic oil and K&N oil filters will keep your engine running like new.

K&N Oil Filter; Billet
  • Billet Aluminum Housing
  • Washable and Reusable
Jason, Sydney Australia
I installed it as per instructions I put PTFE on the o-ring and connecting the filter to the engine it seized that hard that a screw driver and hammer was needed being billet aluminum it didn't like it too much. I was able to re thread it again the canister spins off but left the filter element and connecting piece still on the vehicle both off the threads are a right hand type. I spoke to K&N they were very helpful and resolved the matter immediately. Hopefully I don't have this prob with the second one. The dirt it collected plus the magnets that were visibly able to see was impressive. I still would like to know the microns it filters down too.
