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.

performance

I have used K&N filters for many years because they allow better air flow, burning gas more efficiently- working particularly well with larger engines. It is also good they do not require frequent changing.

Noticeable preformance

My Hyundai Tuscon with 2.4 GDI engine really accelerates better with the K & N filter in place when going up long upgrades and passing trucks. Additionally, went on a 250 mile trip (each way)and got improved gas mileage. Highly recommend it.

K&N Filter

I purchased this filter because I have one in my truck and it makes quite a difference in throttle response and gives me better fuel economy. Even though I have heard and read both good and bad reviews of the product. The thing that I have found with these is that they need to be cleaned and oiled on a regular basis. Otherwise, it may not capture all the dust particles it is intended to keep out.

K&N High Flow Air Filters

A great filter for you vehicle. No more sticker shock from the dealer when the service advisor says, "My technician says it's time for you to replace your air filter" No more sticker shock from the oil change place either. Easy to install and use and maintain until you reach 100.000 mile mark.

The First Thing I Buy For A New Vehicle

I've been a K&N customer for over twenty years. The first thing I buy for a new vehicle is a K&N filter. All of my vehicles have a K&N filter installed in them. Better performance, improved mileage, and a million mile warrantee. It's a no brainier. Just clean and oil every 50,000 miles. Would recommend to anyone.

K&N Air Filters

I've used K&N Air Filters in every vehicle I have ever owned . Soon as I purchase a new vehicle, my first stop is AutoAnything.com and directly to the K&N section to order the Air Filter, and of course a cleaning kit. I love the extra power and the freedom to clean the filter as needed to keep my vehicle running its best !

k & N Filter Review

I bought it hoping I could squeeze another MPG out of my car but that does not seem to be happening. What it does do, is give the car more throttle response. I chose AutoAnything because they had the best price for this Filter. no complaints. arrived within 5 business days.

I use K&N air filters in all of my vehicles. I started using with my motorcycles and now use them in my cars, truck, and golf cart. I clean them every 12-15 months and have not had any problems.

SUPER FIT, SUPER EASY

The product fit perfectly, too easy to install thinner that factory unit easier to install than removing the original. Now I wish I had bough the cold air intake system, this was so easy, i'm sure I wouldn't have any problem installing. Thank You K&N and AUTOANYTHING.

K&N for 12 Elantra

Bought a K&N filter for my 12 Elantra and am happy with the results. Its not a performance sedan so the HP didn't noticeably change much, but did notice the tip in throttle response is a little quicker. The engine noise at WOT didn't change. I've only run two tanks of fuel so can't really comment on the economy...although the economy may have creped up some? One thing for sure, won't have to buy any more air filters for this car, just clean periodically.
