K&N 33-2497 Air Filter Product Reviews

Thursday, January 25, 2018 - Part 33-2497
Bought my 6th, (they've been an addition to my last 5 cars,) K&N Filter for my 2015 Malibu at AutoZone, easy installation, Haven't driven it enough to check mileage yet, but if it's like the other 5 cars I put K & N filters in, I should see a nice improvement. I do know throttle response is a bit brisker. Only thing I was disappointed with, is I didn't get the K&N Decal to put on the car. I got the one that goes on the air cleaner though.

Easy installation. My mpg looks to have went up by about 1.5mpg after installing.

Gasket seal is really tight compared to original filter, (outside edge was a tad to big) had to finesse it into place. Once the lid was on and tightened down it looked like it was evenly sealed. Noticeable increase in performance and fuel economy is better, (2.5 with less than 13,000 miles). I am very happy with price and experience of shopping on the online store. Price was lower than throw away Chinese filter. Thank you! MADE IN USA!

You will always have customers with the product and service you offer. The enthusiast is always looking for more. More power, more appearance, more compliments. Your filters give two of the three, power and compliments. The driver gets the power and your passengers compliment the performance, not to say anything about the increase in economy if you can keep your foot out of the throttle. This is my third street car that I've K&N'd.
