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.

  • Looks good and fictions great!
Nothing but the price to dislike. Great fit and finish. Highly recommend

  • Looks good
Installation was easy enough, but the instructions do leave a few gaps regarding the placement of the screws, but that causes just a brief hesitation. Looks good on my 2012 Electra Glide, but to be honest, other than the optics, I have not noticed any difference in either performance or sound. Subjectively. I did a 3 hole oil change at the same time I installed the K&N and so far I have not noticed any oil blowing out. ... show more

  • It's not pretty, but it works.
I don't love the look but I can tell the difference. Hey, I'm not entering any "aint my bike pretty" shows, I'm here to ride.

  • Sharp looking & great packaging
Looks great, packaging was done proffessionaly and protective. Has all hardware, even included a small disposable bottle of Loctite. Looks good mounted, not sure about added performance yet. Bike is not flashed and i dont plan to until headers are on to complete my exhaust. Did a quick test run and didn’t recognize much of a difference other than the suck noise from added air flow into intake. Sale description said install was 90min or less which was a bit excessive of a high point. If it takes you 90min you should stick to your desk job, at the most it’s a 15-20min process. That includes gathering a couple tools and a run to the fridge for a beer before removing the first bolt. I am going to go with conspiracy theory that K&N may be in bed with some installers so they can charge 90min shop time? Anyway, good job K&N again. ... show more

  • Great breather for my Harley Roadglide
Ive tried a few different breathers on my 2015 Harley Road glide and when this was on sale i had to try it. Install was straight forward with clear included instructions. Parts are quality made and thought went into engineering this to fit perfect. Fit touring Harleys really well. This is my favorite to date. Included pictures. Kit comes with a K&N decal and a emission decal/ tag if needed for your state Inspection. Highly recommended. ... show more

My 2016 Softail Slim S breathes a lot better and looks great also. I get a lot of compliments on the look of it.
