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

  Posted:

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.

  Posted:

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

  Posted:

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

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

pechased the K/N filter assembly for my 2006 Road King Harley. It is every thing thaty I have read about. Installed easy, fits nice, retains the stock look. Performance and workmanship is top shelf I would recomend this product to all.

Beauty ring listed in catalog was missing

Works as advertised.

  Posted:

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

  Posted:

Works great, easy to install.

  Posted:

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

  Posted:

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

  Posted:

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

  Posted:

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
