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.

K&N Filters

Before purchasing this K&N Filter from Auto Anything, I had purchased others for my motorcycles. So I know K&N makes a great product and saw the dyno results on my high performance bikes already. What I didnt expect was the results when I put one in our minivan. It will be a long time before the van can pop a wheelie but right away I was getting 1 to 2 more miles per gallon of fuel economy. For us thats a big deal and adds up at the end of the month. Thanks Auto Anything!!

Filter made a world of difference in my 6 cyl Toyota Avalon.

I changed to this air filter before starting our first road trip in our new car. So far, we've stopped and toured Baltimore Inner Harbor and Virginia Beach; driven 600 miles. We added about a tank and a half of gas ($75). The car reacts really good; getting to 80 mph when entering highway in about 5 seconds. It really has made a difference.

As was expected with a K & N product the quality is there. Cant go wrong with one of their filters. I purchase a cabin & engine air filter for a 2014 Sienna. Instructions made cabin filter an easy installation. Auto Anything had their usual fast shipping. I like to do business with them.

K & N forever

I've used K &N brand filters, ever since I realized how much engines need to breathe. Flat out runs better, and sounds better. From my Tahoes over the years to my wife's Rx350 Lexus.

NEVER HAVE TO REPLACE AIR FILTER AGAIN.

Recently just put into my 2016 Toyota Highlander. Hoping to achieve good mileage and better acceleration. Best feature about K&N is that you never have to replace it. Wash, rinse, and add oil to filter. I look forward to see final results.

Great filter but expensive.

I know K&N has a great reputation but compared to competitors I feel they are overpriced. I have then in both of my cars, this one for a few hundred miles and my other nearly 80,000 miles. The older one still looks new so I guess it is worth the price.

Awesome K/N air filter

K/N air filter gave me more power for my Lexus LS460 v8 and my wife's Rx350 Lexus and for my Beemer 135IM 6 cyl Turbo. All three are more fun to drive now! What a difference it made-More HP and More Air coming in . Thanks to all the crew at AutoAnything! Larry.

Occasionally

I have used K&N filters for many years and I am satisfied with their performance and at the same time have saved a lot of money on replacement filters. I would recommend this filters to anyone who has any kind of vehicle that uses air filters such as car motorcycles etc.
