K&N’s Street Metal Series High-Flow Air Intake Systems provide a good looking appearance, offer increased airflow and deliver more horsepower & torque to your Harley-Davidson® motorcycle. These intake systems increase power by eliminating the stock OE air cleaner and replacing it with a complete High-Flow Air Intake System. The sturdy, custom aluminum backing plate mounts directly to the throttle body via an aluminum integrated, internal-run breather system. The intake system comes with a K&N Air Filter for high air flow and long service intervals. A durable mounting gasket is also included to help absorb vibration. The K&N High-Flow Air Filter is washable, reusable, pre-oiled and ready for installation. Simple designed custom covers give this air intake good looks while powering down the highway or at your local show.

Shipping

SHIPPING IS FREE* for orders of £75 and over , regardless of the weight of your order.
We've tried to keep all other shipping costs as low as we can.

Carriage starts at just £0.95 (inc VAT) for small items, with our most common courier rate set at £4.99 for orders of 5kg (enough for 5 litres of oil).

  • *Free shipping is available for UK Royal Mail, UPS Access Point™ (click & collect) and standard UK courier services (not express / priority / islands).
  • Courier surcharges mean we are unable to offer free "to the door" courier shipping from us in Cornwall up to Highlands / Grampian in Scotland - and because we send a lot of liquids, not every courier option is available to us. UPS Access Point™ (click & collect) is available as a free shipping option across Scotland, Wales and England, wherever there is a UPS Access Point™ Location.
  • Carriage charges are based on weight - please see our table of carriage costs for full details (although adding an item to your cart and viewing the calculated carriage is often easier!).
  • Priority shipping is also available.

How long will it take to get my order?

We give an estimate of delivery dates as you shop and in your basket. The vast majority of items are held in stock and dispatched from our UK warehouse and we'll do all we can to get your order to you as quickly as possible.
