K&N Cold Air Intake System: High-Flow Air Filter, Increase Performance & Acceleration: Compatible with 2001-2017 Harley Davidson: (See Product Description for Selected Models) RK-3953

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.

I ride an 07 HD ELECTRA GLIDE with the 96 ci and I finally spent the money got what I have been wanting and I am so excited about the looks and performance this thing puts out I can’t say anything bad about the K&N kit it does boost the bike up with the amount of air it takes in WELL WORTH EVERY DOLLAR MY FRIENDS

Works as advertised, I felt the power gain right off the bat in torque and horsepower.

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!!!

Does fit on 06 Ultra classic, Instructions are bad , but between utube & service manual u can get it done. Head bolts 10 to 12 foot lbs, the rest of the bolts tighten by hand .

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.

This went on easy and I like the quality of the material.

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.
