Description for K&N RK Series Air Cleaner Kit

K&N has built this R&K Air Intake Series around assisting your Harley-Davidson to get more horsepower out of it with a simple upgrade, so get ready to go fast with their excellent air filtration. K&N has built these assemblies to replace the stock air filter and backplate with their oversized air filter and custom backing plate design per application. Choose between one of the clean covers or go with no cover at all to maintain the stock appearance. As most of K&N's filter elements they have to offer these are washable and able to be reused once they are recharged.

• The K&N RK-Series High-Flow Air Intake System increases engine intake airflow and delivering more horsepower & torque

• The intake system increases power by eliminating the stock OE air cleaner and replacing it with a complete High-Flow Air Intake System

• The intake system comes with a K&N Air Filter for high air flow and long service intervals

• The K&N High-Flow Air Filter is washable, reusable, pre-oiled and ready for installation

• Replaces the stock air filter and cleaner backing plate assembly

• Fits behind the OE air cleaner cover maintaining the factory appearance

• Washable, oversized K&N high-flow air filter equals longer life

Worth every penny! What a difference. Combined this with a set of true duals to replace old ones. Noticed a difference. Fantastic !!

Fits great, K&N quality, bike likes it! Installed along with V&H power duals and V&H Fuelpak 3. Noticeably happier engine. Buy some H &C crankcase breather vents to replace stock. The puff coming from stock breathers almost can follow you into thinking you have an exhaust leak.

Looks to kill, and damn does this thing breath. Before I installed my new exhaust I threw this sucker on. Yep, you can hear a difference. Goes great with all my finned add-ons too.

I have receive my order quite rapidly even I live around Montreal. There was a defect with one spacer and a bolt will installation on the bike and it stock, having a hard time to remove them. I wanted to give a one star for the review. I contacted customer service with “chat”and someone was available immediately. He arranged the shipment of not only the defective parts but a full hardware bag. The installation went very good. I gave them a 5 stars for the the kit and for the customer service.

I have ordered this K&N perforer air intake system about 3 weeks ago. I have receive it fast enough. When I proceed to the installation, i face a problem with one of the spacer and one bolt. The threads of the spacer was not good and the bolt jammed having a hard time removing bolt. I was disappointed and wanted to give a one star to the review. I contact customer service and get on chat a person right away. I managed to send me not only one spacer and one bolt but the full hardware bag, those arrived at home 3 days later in around Montreal. Because of the great service offered, i gave a 5 stars for the product review.
