K&N 66-3320R Dominator Drag Race Air Cleaner Assembly | 9" x 5"

Protect your engine with the K&N Dominator Drag Race Assembly. Featuring a 9" OD, 5" height, and X-Stream top for maximum airflow and superior filtration on the track.

The K&N 66-3320R is a specialized air cleaner kit designed for Dominator-flange carburetors. It features a 9-inch outer diameter and a 5-inch tall washable cotton gauze filter element. The assembly is topped with an X-Stream airflow lid, which adds additional filtering surface area directly above the carburetor for unrestricted breathing. The base is constructed from high-quality aluminum with a black powder-coated finish for durability and a professional racing aesthetic.

Best Uses

  1. Professional Drag Racing: Specifically designed for NHRA/IHRA style dragsters and door-slammers.
  2. Dominator Carburetors: Perfect fit for engines running 4500-series Dominator flange carburetors.
  3. Hood Scoop Setups: Ideal for racers using specialized scoops like Harwood or K&N carbon fiber scoops where space is vertical.
  4. High-RPM Engines: Best for big-block or high-revving small-block engines that "breathe" heavily at the top end.

Features

  1. X-Stream Airflow Top: The lid itself acts as a filter, pulling air in from the top to eliminate turbulence.
  2. Custom Cotton Gauze Media: Uses 4 to 6 layers of premium cotton gauze for high-flow filtration.
  3. Low-Profile 9" Diameter: Designed to fit into compact racing environments and under tight scoops.
  4. Durable Aluminum Base: Features a sturdy, lightweight aluminum base plate specifically for Dominator flanges.
  5. Washable & Reusable: The filter is not a "throwaway" item; it can be cleaned and re-oiled for years of racing.

Benefits

  1. Increased Horsepower: By reducing intake restriction, it allows your engine to reach its maximum power potential.
  2. Engine Longevity: Stops fine dust and track grit from entering the cylinders, preventing premature engine wear.
  3. Cost-Efficient: Since it’s reusable, you save money over time compared to buying paper filters every season.
  4. Easy Maintenance: Can be quickly serviced between race events using a K&N Recharger kit.
  5. Reliable Fitment: Engineered for a vibration-resistant, airtight seal, so you don't have to worry about leaks at 150+ MPH.
