K&N 33-5049 Air Filter Product Reviews

Perfect fit, replaced the OE filter. Great product. All my vehicles have K & N air filters. The last air filter you will buy. When it gets dirty, just use the cleaning & servicing kit available at parts stores, and then you have a clean filter ready for use. Easy. Very respectfully, Rob

I elected to go with a K&N air filter with my 2016 Malibu, since I had used one in my previous car for 10+ years and 298,000 miles without a problem. As expected, it fits like a glove and works as advertised. The best part, though, is that it cost me about $40 LESS to buy this lifetime filter than it would've cost me at the dealer for ONE new air filter installation....and it would need to be done every XX,000 miles. I do a lot of driving, so this very wise purchase will potentially save me hundreds over the lifetime of my car.

Easy to install air filter. Flat blade screwdriver only needed. Fuel mileage increase and slight performance increase noticed immediately. Great buy.
