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

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.

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.

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

5 by

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

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

5 by

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

5 by

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.
