Description

K&N Street Metal Air Intake Systems for Harley Davidson motorcycles replace the restrictive stock OE air cleaner with an oversized K&N High-Flow Air Filter and a high-volume cast aluminum housing. If you're looking for an aggressive appearance but want a significant increase in airflow, resulting in more power, this high-flow air intake system is exactly what your Harley needs. Installation is so simple, it can usually be done in 90 minutes or less. The K&N air filter is washable, reusable, pre-oiled and ready for installation. This intake system features an updated, modern look with an oval-shaped matte black housing. Silver details and sanded fins further enhance the streamlined look. Internal breathers provide a sleek, clean appearance. This air intake has a classic styling with a savage appeal. These K&N air intakes are street legal in most states. They are not legal for use in California and other states adopting California emission standards.

Very solid AC and easy install
Review Image by MOONRUNNER MOONRUNNER
Home run. Looks awesome, easy install, and these filters last forever. The first one I got was the wrong one in the right box... obviously an Amazon return that they didn't check, because the box and internals had all been gone through and greasy fingerprints were on the instruction sheet. Somebody bought two different ones because they didn't know which one fit their scoot, then returned the unneeded one in the wrong box. Took 2 days to get the right one sent but that's on Amazon, not K&N. ... show more

Follow the directions to a T
Power increase is a definite, seat of the pants feel... Very clean look on my 100th anniversary Road King... I'm here to tell you it is a very confusing install and the instructions are kinda vague but if you have any kind of mechanical skills it can be done... So worth the money!!!

quality construction materials
Review Image by sarge sarge
Good-looking on my 2004 FXST/I, complements the engine cylinder fins. CON: the weight is quite heavy , but as headline indicates durable construction material is been used to manufacture their product.

Great product but be careful of comfort.
Ok so this is a very nice air intake for a great price. All of the components are well made and fit well. I work as a machinist and can tell this is top notch. The cover is especially good looking. Install is easy if you have basic mechanical skills and the correct included parts (everything was good for me). I definately noticed a solid performance increase over the stock filter and even an AN stage 1. Unfortunately it is very large and hits right on my shin with my riding position. I'm a light 5'6" dude riding mid controls on an 08 fxdl if that helps. It might be ok for most but not me. Unfortunately I have to return it but I am going with another K&N product that fits my riding style better. As long as it doesn't get in the way I would suggest this all day. ... show more

Looks and rides great.
Don’t listen to the bad reviews about it being hard to install. If you can figure it out you most definitely shouldn’t be on a bike. Looks amazing on my street bob.

Piece of junk and worse customer service
Don't buy it! I've heard bad things about K&N being a rip off, but I went ahead and bought one. It's junk, customer service took two weeks to respond to an email and couldn't even get that right. I called the 800 number for replacement hardware that failed and I got a big box with loose screw(singular). There might have been more but who knows they were just thrown in a 8"x8"x6" box with no packaging. $145 of failure and disappointment. I'll never give them another chance. ... show more
