Description

K&N Universal X-Stream Clamp-On Air Filter | 3" Flange, 6.5" Height

Boost airflow and performance with the K&N Universal X-Stream Clamp-On Filter. Features a 3" flange, X-Stream top filter, washable design, and a lifetime warranty.

The K&N Universal X-Stream Clamp-On Air Filter is engineered to deliver maximum airflow, outstanding filtration, and noticeable performance gains. Unlike standard air filters, this X-Stream model incorporates a filtered top alongside its perimeter walls, drastically increasing the total surface area and maximizing air intake potential—ideal for tight engine bays demanding high volume.

Built using K&N’s signature layered, oiled cotton gauze media, this filter efficiently captures harmful contaminants while reducing intake restriction. The ultra-durable, pliable rubber flange absorbs vibration and allows for a secure, custom fit on standard 3-inch intake tubing. Fully washable and reusable, the X-Stream filter is designed to last the life of your vehicle or custom build, making it the ultimate upgrade for automotive enthusiasts, fabricators, and racers.

Best Uses

  1. Custom Intake Systems: Ideal for custom cold air intakes, turbo setups, or supercharged builds requiring a 3-inch inlet.
  2. Track & Racing Applications: Perfect for performance vehicles where maximum airflow directly equates to horsepower gains.
  3. Engine Swaps & Hot Rods: Designed for tight or custom engine compartments where space is limited but intake demand is high.

Features

  1. X-Stream Filtered Top: Integrated top filter adds surface area to drastically increase total airflow capacity.
  2. Pliable 3-Inch Flange: Flexible, ultra-durable rubber flange absorbs vibration and fits snugly onto standard 3" outer-diameter tubing.
  3. Layered Cotton Gauze Media: High-flow oiled cotton construction designed to capture contaminants while minimizing airflow restriction.
  4. Washable & Reusable: Engineered to be cleaned and re-oiled repeatedly with a K&N Recharger kit, eliminating single-use replacements.
  5. Heavy-Duty Construction: Molded rubber end caps and a zinc-coated steel clamp ensure structural stability under high vacuum pressures.

Benefits

  1. Increased Horsepower & Acceleration: High-flow design reduces intake restriction, allowing your engine to draw air faster and work more efficiently.
  2. Superior Engine Protection: Multi-layer filtration blocks fine dirt and debris to safeguard engine internals without choking airflow.
  3. Cost-Effective Lifetime Value: Reusable design means you clean it instead of replacing it, saving money over the life of your vehicle.
  4. Optimized for Tight Spaces: Compact dimensions (6" Base OD, 5" Top OD, 6.5" Height) deliver big-filter airflow in constrained engine bays.
  5. Eco-Friendly Choice: Eliminates disposable paper filter waste in landfills by offering a permanent filtration solution.
