  • Designed to Increase Power
  • Million Mile Limited Warranty

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.

This was a little tight on my 1998 Nissan Frontier but 4/5 of the clips are secure so good enough. Would take off a star but K&N generously included some air filter grease that is sufficient for multiple installs

Superior product! Got this for my 2003 Nissan Frontier with the KA24DE 2.4L I4 engine. Shipping was good, came in about a week from ordering. Installation was super-basic, no special tools or anything but the best thing was the performance gain. I could feel noticiable gain to both torque and HP. I believe this product will stand up to the Million Mile Warranty!
