Description:

For more than 30 years, K&N cold air induction and cold air intake filters have been the choice in engine filtration. Designed to deliver virtually unrestricted flow to help your engine run stronger, cleaner and with greater fuel efficiency, K&N Air Filters are pre-oiled and ready for installation in your specific year, make and model.

The secret is in the filter medium – four to six sheets of pleated and oiled cotton-gauze are layered between two sheets of aluminum wire mesh. This tried-and-proven design traps dirt, dust and other harmful particles, while clean, power-enhancing air flows freely to your engine.

KN Air Filters require only a simple cleaning every 50,000 miles, and with no costly changes or services required, it saves you money in the long run. You’ll also help the environment in the long run by reducing the number of disposable air filters that wind up in our nation’s landfills. Street-legal in all 50 states, your K&N Drop In Filter is covered by a Million Mile Limited Warranty.

Notes:
Moss Warranty Act Statement

Thanks to the Magnuson Moss Warranty Act: US Code – Title 15, Chapter 50, Sections 2301-2312, your vehicle’s factory warranty is protected by law when you add aftermarket parts.

Everyday Driver

Noticed more pick up and go right away. Slightly better mpg. I'd say about 1 mpg increase if you keep your foot out of it. Have used kn products for a long time and would recommend them to any application.

Added power and fuel economy

With the K&N filter I'm seeing an average increase of 0.5 MPG, and definitely feel the difference on acceleration. It's nice to see fuel lasting longer with today's crazy prices.

worth it

A worthy upgrade for any performance oriented vehicle. We have a 2011 Frontier 4x4 with a big honkin' V6, a 2012 Juke AWD SL, and a 2014 Juke Nismo RS. The filters are insanely expensive, so if you don't keep the vehicle for at least 80-100,000 miles you will not recoup your purchase price. But in the mean time you enjoy a mild performance gain.

Best opption to OEM replacement

Perfect fit and easy installation the last filter I ever need for my wife's rouge. Why modify when your vehicle already has a cold air intake.

2012 Nissan Juke AWD

A lifetime filter for the cost of 2 or 3 paper filters. Not sure on the interstate, but it added 2 or 3 mpg at 60 to 65 mpg. Mileage was the main goal. I don't know about power, it definitely didn't hurt, seemed to pull out to pass a bit quicker. Simple installation, it took 5minutes,

Another K&N Purchase

This is the fourth K&N filter that I have bought for several vehicles over the past few years. Always happy with with the product. I replace the factory filter with a K&N filter every time that I purchase a new car.

Great quality life time air filter

I have been using paper air filters and this is the first time I use K&N air filter. First impression when receiving the product was that the quality build of the filter that is for very long lasting. Though it costs triple the paper filter, it will pay for itself after 1.5 year as I tend to change my car air filter every 6-7000 miles for better performance. My 2013 Sentra seems to accelerate better even on ECO driving mode. Will probably buy K&N air filter again for my Expedition. Recommended.

Cheap Performance Upgrade

I have used K&N air filters on my last four cars. I have always experienced the same performance boost after installing one. My gas mileage goes up between 1 and 2 miles per gallon, and I have tested and verified about a 3%+ increase in horsepower. One note to consider. Even though the filters are life-long permanent filters, they do require at least annual inspection and servicing, more frequent if you live in a dusty climate.

Time will tell

So far so good, but since it's only been in for a week or so, hard to gauge. Based on what I've read about the K&N product, I'm confident I will be happy with the purchase. Thanks.
