K&N 33-2233 Air Filter Product Reviews

I have always used these filters, and I find them great. At present I have one in a Jeep Liberty 2.8 CRD 2007. I will always continue to use these products, as they're well made and have a long history. I also use K&N oil filters.

This is the 3rd K&N product I've purchased. I expect it to last/perform as well as the other 2.

Bought my filter a little over a month ago. It's fantastic I have a 2006 Jeep Liberty. I take great care of it, had been noticing for quite a while that it had a lag when I accelerated. It was especially concerning when I need a little power in heavy traffic to get an opening. I noticed an immediate difference after my new K&N filter. Not only did I lose the hesitance on initial acceleration, but it has better all round pickup. A significant difference Small investment for big results. Best investment and very happy. Thank you.

Perfect fit Amazing product Works great Gives me more horsepower and better gas mileage. I own a 2010 Jeep Grand Cherokee 4x4 and it's the best product that I have bought so far for my Jeep.

I've only had this filter in my 2002 Jeep Liberty for several weeks, but I really do think I can tell a difference in power. Time will tell whether it improves my mileage.

For the price of just over two standard filters, this pays for itself.
