K&N 38-2022S Air Filter Product Reviews

Excellent filter. I have now put them on both my hd trucks. First one saved me hundreds on replacement filters by washing it.

I have bought K&N filters in the past as well, so this time I decided to try one for my semi-truck. After installing it, I noticed the truck breathes better, and has a different sound. I drive through some pretty dusty areas sometimes, and the paper filters couldn't do it. They would get dirty, then I would have had to sort of wait until the interval was out in order to replace it. This filter, however, I can clean and wash whenever I go home, if it's necessary. Great product.

This is an excellent HD filter. I use it on my 08 Peterbilt 386 with ISX cummins in it. With the restriction gauge, my old paper filter pulling hard, read about 5 and with the new K&N filter, it is at 2.5. It seems the engine receives better, non-restricted air, then with the paper filter. I just have 5000 miles since i put it in, but i am very happy with it. Thanks for a very fine product. James.

I think your filter is GREAT. You guys should go to Peterbilt and ask to be put on every truck built or at least made as an option!!!! I have a 2013 Pete with a PACCAR MX eng. Didn't change fuel mileage but Power is up Very NICE. So bottom line is more power without anymore fuel COSTS!!!! I am looking to put K&N on everything! I just wish I did this before. THANKS!
