K&N Drag Racing Base Mount Scoop Filters - Now you can protect the motor in your drag car from dust and debris on the track and in the pits with this base mount scoop filter. Designed to fit specific scoop designs popular to drag racing today.

K&N Drag Racing Scoop Filters

Now you can protect the motor in your drag car from dust and debris on the track and in the pits with these filters.
These units are engineered with two filter elements to provide maximum airflow and protection.
Designed to fit specific scoop designs popular to drag racing today.

Inside Scoop Mount Filters

Inside Scoop Mount Filters mount inside the front lip of the scoop and are held in place with Dzus fasteners.
Oval dual element filter fits the Harwood scoop model 3175-15.
Round dual element filter fits the Quarter-Max® hood scoop.

K&N Racing Cone Filters

These filters are designed for the popular Formula Atlantic and Super Vee style cars, used in racing today. The filters fit into the air scoops and allow plenty of fresh clean air to enter the engine, but keep the small stones, tire dust and other racetrack debris from demolishing the engine. There is a hole at the small end of the filter to allow debris to exit the air scoop. Used by top teams around the country.

K&N air filters with the suffix of R have just two layers of cotton to provide even lower air restriction than our replacement air filter for street vehicles. Unlike K&N replacement air filters, fuel management modifications will be necessary with this racing filter. K&N racing air filters are washable and reusable and come with a one year limited warranty. This product is for closed course competition use only.

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.
