I added the K&N air filter to my 2013 Ultra Classic along with a V&H fuel pack and V&H Slash Cut Ovals and what a difference!! The bike is an animal now and runs a little richer...good thing! I like the fact that you can use your stock air box cover, too. Highly recommend if upgrading from stock pipes. Amazon's service and price are 2nd to none!

This did seem to improve airflow and will reduce maintenance cost over time but the surprise to me was that I noticed an increase in gas mileage, to the tune of 2-4 miles per gallon. Installation was a breeze and it may be my imagination but my bike felt a little more powerful off the start.

it's a K&N air filter for about half of what Harley, Advanced Auto and Autozone wanted to charge me and they had to order it anyway do the research and look and what true differences are people will try to sell you stuff you may not need but this product for me and my 2013 FLHTCU is just fine. i will suggest it to anyone looking to buy one

I like K&N filters. Good filter for the money and easy to maintain. I prefer oilless filters for vehicle with turbos, especially diesels as any dirt that gets through can be really hard on the turbo charger. This is for my Harley and performs well.

What can you say, better flow and you save lots of $$$$ by not getting the air cleaner kit and just installing this in place of the factory filter and if you want, you can drill some more holes in the factory air box.

Go to any drag strip and K&N air filters are about all you see for a good reason. One piece of advice I'd offer those not familiar with their existing air filter: When you take the stock filter off do it in a well lit area so it's easy to keep track of the 3 "O" rings that are on each of the 3 mounting bolts between the air filter and the backing plate. If you handle them carefully they can be reused. You don't want to mount the new filter without them. Or, you could make an extra trip to the HD dealer if you'd prefer.

I purchased a new 2011 Harley Davidson FLHTCUTG Trike. It has the 103 engine. As with all our vehicles, we use K&N whenever a K&N is available. Every filter has outlasted our vehicles. I am sure this will be the same. You will be able to install this with ease. You will notice a difference. Get cha one!

This filter is a direct replacement filter to the stock filter that came on my bike. Installation is a breeze. Filter will last forever. I have not noticed any significant performance increases by using this filter.
