The K&N Air Cleaner was very straightforward to install, and was complete. It is unobtrusive on the FXDX and works well.

tms427

The K&N filter assembly installed easily using the simple to follow instructions. The filter lets the engine breath easier giving it better throttle responce and it retains the stock look.

Datundra

Easy to install and makes the bike look better and also increases performance. Great Product.

sboeder

The K&N high flow air cleaner was easy to install and significantly improved the air intake and performance. The size of the air filter did not extend further than the original equipmet air cleaner. The installation instructions were accurate and easy to follow. I am glad that I chose the K&N air cleaner.

royboy2

Easy installation, a must for any V&H pipe and FuelPak.

KevinKelly

Fairly easy to install.Noticeable horsepower increase and throttle responce.

cgill326

capt7453

larrygoju

ldduncan

Straight forward installation. Good instructions. Think the design could be better. Improved throttle response. Happy with the purchase. Have K&N in all vehicles.

Outlawlif3

Very happy with this purchase easy to install took 20 minutes tops. Sounds good and noticeable increase in power.

conranj

Works great, easy to install.

robertsd@howardelectricwb.com

Easy install. Was able to use stock air filter cover.

scmmings

Easy install, and could tell a difference! I'd recommend this, if you want to still keep the "stock" look.

cblesch

You need to have the stock throttle body support bracket still attached to be able to install this kit.

fop81@aol.com

Super easy install. I like being able to use my stock breather cover. Keeps the water out and nobody knows what you have. I added a super tuner to take better advantage of kit

ayersbj@yahoo.com

really impressed with this kit. Awesome fit and makes bike run alot better. Make sure to get some stock breather bolts if you have any other kind of filter installed.
