Description

K&N X-Stream Top Assembly 9" OD 7.313" Neck Flange 3" H High-Flow Air Filter

Boost airflow and horsepower with the K&N X-Stream Air Filter Assembly. Features a 9in outer diameter, 7.313in flange, and 3in height for maximum filtration.

The K&N X-Stream Top Assembly is engineered for drivers and racers who refuse to compromise on airflow or engine protection. Traditional round air cleaners pull air strictly through the side perimeter, leaving valuable intake area untapped. The X-Stream design solves this bottleneck by incorporating a fully functional, pleated K&N air filter directly into the top lid assembly.

Featuring a 9-inch outer diameter, a 7.313-inch neck flange, and a 3-inch height, this assembly feeds cooler, high-volume air straight down into the carburetor or throttle body throat while continuing to draw through the side filter element. Constructed with multi-layer oiled cotton gauze sandwiched between protective wire mesh, the X-Stream offers low restriction and exceptional filtration efficiency. Built to withstand high-vibration racing environments, it is washable, reusable, and built to last the lifetime of your vehicle.

Best Uses

  1. Performance & Racing Applications: Ideal for drag racing, circuit racing, and off-road setups where unrestricted intake airflow directly translates to throttle response and power gains.
  2. Carbureted & Throttle-Body Fuel Injected (TBI) Engines: Fits custom builds, street rods, and muscle cars equipped with standard round air cleaner bases matching the 7.313-inch flange standard.
  3. Engine Compartments with Tight Hood Clearance: Perfect for tight engine bays where vertical space is limited, as the integrated top filter maximizes air intake without requiring a taller filter body.

Features

  1. Integrated X-Stream Filter Lid: Replaces standard solid metal lids with a high-flow pleated filter surface to pull air directly from above.
  2. High-Flow Oiled Cotton Media: Made with multiple layers of woven cotton gauze pre-oiled to trap harmful dust and contaminants without restricting airflow.
  3. Precision Dimensions: Engineered with a 9 in (229 mm) Outer Diameter, 7.313 in (186 mm) Neck Flange, and 3 in (76 mm) Height for a precise fit.
  4. Washable & Reusable Construction: Fully compatible with K&N cleaner and oil kits, eliminating the need for single-use paper filters.
  5. Durable Wire Mesh Shielding: Epoxy-coated aluminum wire mesh protects the filter media from debris impact and structural deformation under heavy engine vacuum.

Benefits

  1. Maximizes Air Intake Volume: Draws air from both the sides and the top, delivering a significantly higher volume of air compared to standard flat-top assemblies.
  2. Improved Throttle Response & Power: Reducing air restriction allows your engine to breathe easier, helping unlock additional horsepower and torque across the RPM band.
  3. Long-Term Cost Savings: The washable design allows you to clean and re-oil the filter for years of service rather than repeatedly buying replacements.
  4. Superior Engine Protection: Premium multi-layer filtration traps micro-particles before they can reach your engine's internal components.
  5. Space Efficiency: Provides the airflow capacity of a much taller traditional air filter assembly within a compact 3-inch profile.
