    With increased airflow and a reusable element, K&N Air Filters are created to increase performance while still filtering out debris and particulate matter. With these filters you’ll get an engine that runs more efficiently, creates more power, and is much more convenient when it’s time to clean your air intake.

    That’s because one of the largest benefits of K&N filters is their reusability. When your filter gets dirty, simply wash, dry, oil, and reuse the same filter. It will retain excellent performance and be as close to new as possible. Best of all, when you put the performance of a K&N air filter in your machine, it will fit into your stock air box without having to make any modifications.

    Specs:
  • K&N air filters offer high air flow with excellent filtration
  • Air filter designed to increase horsepower and acceleration
  • The K&N air filter is washable and reusable.
  • The air filter is an easy, high performance add-on
  • K&N air filters are environmentally friendly
  • No modification needed to your stock air box
  • Filter cleaner and oil available (sold seperately)
  • Cleaning and oiling instructions available in videos above

Great product
After having a couple of after market foam filters I spent the extra dollars for the K&N. it seals very well against the base with no guessing if the foam of the others is in place. I have cleaned it several times, each time I give the post filter take a white glove treatment and have not found the slightest trace of dirt getting past the filter

K&N Filter
Guys poo-poo K&N filters all the time and say they don't work well for off road applications. I've been using K&N's for 30+ years in the dry dusty Southern California deserts and have never had any issues. Keep it maintained and it will out perform and outlast any other filter on the market.

Worried Dirt rider going switching from the standard foam filter
I was worried about putting this on my dirt bike as foam filters are the norm when it comes to dirt riding. I was also adviced against this purchase from just about every dirt rider I know. However, I said wht the heck and gave it a shot. It was easy to install and perfectly snug. After using this for three years now, my worries are no more. It's easier to maintain, clean, and does give a bit of a bump from the stalk filter. No matter how dusty or muddy my rides have been, the air box under the filter is completely clean. I personally like this more than foam as it does not required to be cleaned after every ride.

Love K&N filters.
I run K&N filters on everything we own, so it makes perfect sense to run it on my Kingquad. It costs a little more than the stock filter but I'll never have to replace it again. I definitely feel an improvement but not sure if its related to the new iridium plug or the filter.

Do I need to oil this air filter before I install?
Thomas B on Apr 18, 2017
BEST ANSWER: No, comes pre-oiled out of the box ready for use.
What are the dimensions of this filter ?
A shopper on May 15, 2017
BEST ANSWER: What machine would this be for?
Hi, will this fit a 95 Polaris Explorer 400 ? Thanks Paul.
Paul M on Jul 18, 2017
BEST ANSWER: Paul, thank you for your questions. I looked into this and we don't have this listed for the 1995 Xplorer 400. However, we do have this air filter for the 96 Xplorer 400 which is the same one in the '95. You can go ahead and order the '96 filter for this machine and it will work just fine.
Does this fit in the stock air box like a stock filter? and can it be used with the outter wares?
David M on Jan 8, 2017
BEST ANSWER: Hi David, yes it does fit in the stock airbox of the Yamaha but to install and remove, instead of the 1 bolt for the stock filter you need to remove 8 bolts and the ones on the bottom are a pain.
does this come with the pre filter?
A shopper on May 7, 2018
BEST ANSWER: I had to purchase the pre filters
Does it come with the air filter sleeve also?
A shopper on Apr 30, 2019
BEST ANSWER: No the one I got for a KTM 690 does not. But a great filter
Installing on a kfx 700, do I need to up the size of my main jets to compensate for the increased air flow? Thanks
Gil S on Mar 7, 2017
BEST ANSWER: With just an air filter change possibly not. A lot of other factors determine answer of this question. Exhaust, altitude, air box. Run it and check a plug and running condition. Worse case may have to go up one size on jet in each carb ( you have two)
Will this fit 2018 yfz450r quad . Stock air box and intake?
James C on Jul 30, 2019

If I put the K&N air filter in my 2018 701 Supermoto do I have to re jet my carb?
John E on Jul 25, 2019
BEST ANSWER: I own a 2016 Canam Outlander 1000XT. I did not have to change anything else on mine. However my ATV is fuel injection. Sorry I cant help better than that
Do you sell an outerwear for this filter?
John A on Jun 29, 2019
BEST ANSWER: There many types of covers for this filter and have one on my filter. I also run a s&b filter particle separator. The reason I run the s&b is I have ruined a filter in one trip went I was on a trail that had about a foot on power as fine as talcum powder.
I’m installing in my 2012 Suzuki kz400r and am told being fuel injected its automatically re-jetted. Is this true?
Glenn K on Nov 4, 2018
BEST ANSWER: Fuel injection is not affected by changing filters. I use the k&N because the dust where I ride required a new filter after each ride.
If I am installing this filter in a 1996 Honda TRX300EX, will I need to install it with the OEM filter body (that is the round inner metal screened filter that the OEM foam filter slides over)?
Joe C on Dec 3, 2017
BEST ANSWER: I installed mine on KLR650 Kawasaki motorcycle, it did not need the OEM foam filter cage...
if i get a yoshimura full exhaust system and a k&n air filter on my 09 kfx450r will i need to get an efi tuner and/or do something to my jets? thanks
marc l on Oct 14, 2017
BEST ANSWER: I would for sure do the jets. It will be getting more air so you would like fuel to match. I think the tuner could be an option, and could really wake up that motor.
Is this for the primary filter on YXZ or secondary?
Robert M on Sep 24, 2017
BEST ANSWER: Primary
