This product in my opinion is by far the best. I have been using K&N oil filters (along with synthetic oil) in my 2000 Nissan Frontier since about 20,000 miles. I am currently at 154,000 miles and have never experienced any oil related issues, ever. The welded on nut is so nice especially with Nissan's location of the filter not being the most easily accessible. PS: I also use K&N filters for my motorcycle. Keep up the good work. K&N for LIFE!!!!

I am REALLY HAPPY with my K&N Cold-Air Intake!!! It has boosted the gas mileage on my 2005 Nissan Frontier 4.0L 4WD Crew Cab Pick-up from 15.3 to 21.1 mpg when I drive it like I have good sense! It still beats 15.3 when I'm in a hurry and has a very enjoyable throaty scream to it when I kick it to pass those that are taking their time! There's also no denying that the HP is up substantially! All in all I would have to give it 5 stars only because that's the most stars I could choose. Hey, wait a minute...I'm the one writing this review and I'm giving it 10 stars! There, that's better, LOL. The people at K&N have made a believer out of me...even the install was a piece of cake as I was all done in under an hour due to the well thought out directions. Bottom line: K&N Rocks!!!

I found this very helpful on my 12 Nissan Frontier when trailering my boat...there is a definite HP increase at higher RPM's when climbing hills.
