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.
