Trucks runs better and has more power.
Terry Leland, Kailua Kona, Hawaii
I have used K&N filters for my motorcycles and know they are very good. When I replaced my truck a/c, my fuel mileage went down by 20, after replacing the stock filter with a K&N my mileage increased by over 2 miles per gallon and a nice little power increase, not much but noticeable especially with the a/c on.

Purchased this a month after I bought my 2001 Nissan Frontier which now has 130K miles. Adds Torque and HP since I have an automatic transmission. Wash and clean this filter 3 times so far and still looks as good as the day I installed. I wash the filter every 35-40K miles to prolong the life of my engine as well as keeping this filter clean.
