I went from a hoopty, to a whahoopty!
My '01 Frontier is now a high performance machine! Ok, not really. There is definitely a noticeable difference since I installed this filter though. My gas mileage and power have improved.

Got an additional 1 MPG and better throttle response in my 2013 Altima 3.5S
A perfect drop-in fit for my 2013 Nissan Altima 3.5S with factory air box and intake. Throttle response was noticeably improved over clean/new factory paper filter, ESPECIALLY at lower RPM (which this engine w/ the CVT tends to prefer). You'll notice throttle response increase much more than an overall power increase. MPG climbed right around 1 full mile per gallon (hovering between .9 and 1.1 additional from my calculations at the gas pump and the in-dash display). Intake growl increased a little when really getting into the throttle, but is same as stock when you're not driving aggressively. If you have a CVT (Altima, Maxima, Murano, Pathfinder, etc.), then this seems to make sense due to the improvement in throttle response (how power applied to the wheels tracks with pedal movement). If you're in a truck with the std 6-speed auto, then it may not make much of a difference other than tripling your filter change interval. Going from 27mpg to 28 mpg will pay for the filter alone (I already have a recharge kit from K&N, also found here on Amazon).Don't expect miracles, but it's a quality product that delivers reasonable return on investment. If you drive like a fool, don't expect your MPG to go up. But you will enjoy the slight noise improvement and the throttle response.

Quality
You get what you pay for with K&N products. Have purchased several K&N air filters before and keep coming back to them. Quality and long lasting.

Deliveres good response
This K&N filter is very good, you can notice a small difference in acceleration and response from the SUV. It did help much with the gas mileage but it did for the performance. Good product!

Best way to go
Perfect fit for our Murano. Nissan dealer wanted $43 for one that had to be replaced every year.

Worth the extra money
Our dealership wanted to charge us $150 to change our engine air filter. This has to be one of the easiest maintenance items a car owner can do. I decided on the K&N because I like the idea of a washable / reusable filter. Easy to install, easy to clean. Overall a great product.
