K&N 33-2489 Air Filter Product Reviews

Love the delivery. Ordered Tuesday before noon, received next day. Product is drop in ready. Fairly easy to clean ( takes a bit of time to dry. I use a paper one as the K&N dries ) Gives the car just that little extra power for no money. I also use the oil filters by K&N.

High level of quality of material and workmanship as expected. Also, though no scientific tests were done, product seems to perform as expected. Very satisfied.

Too early to know for sure. I do like the ability to reuse the filter and save money in the long run. Many people don't know how easy it is to replace your own cabin filter. Most dealers charge $80 and up to do a 5 minute job. My neighbor was going to pay $85 to have her's replaced in a Honda CRV. I said...No you are not going to pay that, It's a rip off I had an extra factory filter, and I showed her how to change it....then made her do it.  Simple I'm not sure about the fit of this filter. It didn't seem to go in it's slot as easily and securely as stock filters.  Might be just me.  Not sure.  I've replaced many cabin filters in different makes of cars.

Delivery was on time and as usual, the product is top of the line and very affective. Cold air system is next.

This product is superb / excellent. My 2016 Acura RDX AWD became more responsive and added few more horsepower. My engine can breathe more freely. And you can really feel the difference. I highly recommend K&N Air Intake Filters to everyone. Try it and you will never ever say goodbye..
