Trucks runs better and has more power.

Works great. I installed it in a 2002 Nissan Frontier (230,000 miles) and noticed an immediate improvement. My engine used to turn 3000 rpm at 70 mph, now it turns at 2800 rpm. I have to cross a steep bridge every day and I used to have to gear down to fourth, but now I can stay in fifth gear and cross it with just a slight increase of throttle. I was so impressed that I bought a K&N filter for my mother's 2005 Expedition and also noticed better performance. I wish I would have done this sooner. Over the life of my vehicle, it would have saved me a lot of money in gas and put less strain on my engine and transmission.

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!
