K&N's RK Series was developed to get more horsepower from your Twin Cam Harley-Davidson engine. Built around the legendary K&N High-Flow Air Filter, the this RK Series assembly includes an innovative powder coated billet aluminum backplate that eliminates external breathers and features a built-in, dyno-tuned velocity stack. The result is a significant airflow increase to the engine without sacrificing filtration. This RK Series assembly retains a factory appearance by utilizing the stock air cleaner cover. The RK-3910-1 comes with a larger air filter and longer spacers than the RK-3909-1. The latest addition to K&N's RK Series was developed to get more horsepower from your Twin Cam Harley-Davidson engine. Provides a significant airflow increase to the engine without sacrificing filtration.

HOW TO RETURN AN ORDER

To return an order, please contact us HERE, with detailed information regarding the return. We can only accept items that are in new condition and have never been installed. We cannot accept any used, previously installed, or damaged items. If an item is sent back to us used, previously installed and/or damaged, it is now the property of Just Bolt-On Performance Parts and no refund will be issued. All returns must include the provided Return Merchandise Authorization (RMA) form or RGA number, to help expedite the return process. We will then provide the Return Shipping Address for the return. Pictures of the parts being returned are also required. All returns are subject to a 20% Restocking Fee of the original purchase price.

The buyer has 30 days from original purchase to initiate a return RMA and forward tracking information to us. No refund will be given for products that arrive after the 30 days from the original purchase date. Tracking information is required for all returns. When shipping an item back to us, we recommend that you use UPS, FedEx or any other carrier that offers signature confirmation and insurance, as we are not responsible for lost or damaged packages. Only the signature of an Just Bolt-On Performance Parts employee will suffice as proof of delivery. The customer agrees to bear all shipping and insurance charges, and all risk of loss during return shipment. If an order is refused “Returned to Sender”, no refund will be issued. Buyer is responsible for all return shipping charges.

We will not accept a return of an item that is damaged or defective if it has been used/installed, please inspect all orders as soon as you receive them and contact us HERE within 72 hours. If the order is damaged during shipment, Just Bolt-On Performance Parts will replace the item free of charge. 

When you purchase items that qualify for a promotional offer such as Buy "X" number of items, Get "X" number of items free, the discount reflecting the price of the lowest-priced item is proportionally applied to each eligible item. If any item is returned, the refund will be equal to the original price of the item reduced by the proportional discounted amount.
