Surprised on increased surface area over the stock filter. Should help with air intake. Easy to install and just took minutes.

Great buy!

By   on  Verified Purchaser

Always been a K&N fan and this one for my 2014 Interstate didn't disappoint! Granted it's coupled with Cobra Speedster pipes and a Cobra Fi2000 fuel processor, definitely delivers the air flow needed without changing the factory intake. Great fit! Great price! Ride on!


Performance and great value!

This filter was a perfect replacement for my Rancher, allowing increased air flow and performance! K&N has always been my choice in every application.

I can hear it sucking air! Awesome product bit pricey.


Great product

By   on  Verified Purchaser

I love the filter pretty quick delivery and easy install. Just the filter shows a difference in the bike performance and by taking the air box lid off is even more of a difference. Overall I give it 5 out of 5 no questions asked.


Ltr 450 filter

Purchased to replace the old k&n filter and it was the exact fit!


Do not follow instructions

By   on  Verified Purchaser

The filter definitely makes the engine breath more. Although for a $60+ dollar filter there should be metal inserts where the bolts go through the filter, trying to torque the bolts to the spec provided by K&N, the filter cracked and broke through one bolt holes.

Everything you expect from K&N

By   on  Verified Purchaser

Received these air filters very quickly. Was very easy to install - took about 10 minutes. They are giving me everything I expected from K&N. Note* The first 10-15 minutes of use, motor running, I got that brand new air filter smell. Not pleasant, but after a few minutes it was gone.


Good filter

By   on  Verified Purchaser

Replaced OEM filter with this, and noticed absolutely no change. That's a good thing, I didn't want it to affect my carb tune. The snorkel/airbox probably creates enough restriction that it nullifies the effects of any "high flow" filter.


Great product

K&N products are the only way to go.

good fit. fast delivery


Love it

By   on 

K&N air filters are great because you can use them over and over and long as you clean and re-oil. Put K&N's on all my vehicles. The long term benefit in K&N is cheaper than normal air filters. Even a dirty K&N air filter has better air flow than a conventional air cleaner and the fuel consumption could be 1% to 5% better.

Questions & Answers

Ask Question

How do you clean and re oil this filter?

K&N makes specific cleaner and oil that you can get individually or in their Recharge kit. You would clean and dry the filter as specified in their directions to be able to oil it for reassembly.

By Andy
Answer Question

Are this fit on ninja Ex650 E 2012 ?

Yes, just be sure to choose the correct year/make/model machine before adding to your cart to get the correct filter.

By Andy
Answer Question

Do I need to buy a foam cover for this like the original air filter had over it?

Buying this for a 2005 yamaha grizzly 660 4x4

There's no need to re-use the OEM foam filter cover when installing this K&N air filter for the Grizzly 660 ATV. No less, if you ride in particularly dusty areas, you may want to add a K&N air filter PreCharger to your order so as to increase the time between service intervals on that filter.

By Staff
Answer Question

Will this product fit 2005 Kawasaki brute force 750 4x4, thanks

Yes, if you were to choose the 2005 Kawasaki KVF750A Brute Force 750 4x4i from our fit guide that's immediately to the left of the main image on our website, you'd receive the correct Brute Force air filter to fit your machine.

Answer Question

Maintenance

How often would I have to re-oil?

Generally speaking, K&N filters only need to be re-oiled when you clean them. This can be up to 50,000 miles, depending on when/where you're riding your machine. If you're constantly riding offroad, then you'll want to clean it more frequently than that. The best way to tell when your K&N air filter needs to be cleaned and oiled is when you can no longer see the wire screen that's used to hold the filter's gauze in place. For some riders, that's after more than 50k miles, for others, it may be less.

By Staff
Answer Question

This would fit under the stock cleaner cover correct

Yes, K&N air filters we have for sale here are designed as an OEM-replacement type filter. They fit in the same place as the original filter element that comes on the bike you select from our fit guide.

By Staff
Answer Question

Do you need a tune after installing?

To say for sure, it really depends on what machine it is that you're installing it on. In most cases, and especially with modern fuel-injected bikes, it's usually a non-issue; you won't have to tune fuel delivery. For anything that's carbureted, you may want to consider adding a Dynojet Carburetor Jet kit to your order. In this way, you can be sure to get fuel delivery dialed in properly to work with the new air filter.
