9in X-Stream Filter Top

The K AND N ENGINEERING 9in X-Stream Filter Top is a premium air cleaner lid assembly designed for hot rodders, custom builders, and performance-focused enthusiasts who demand both aesthetics and function from their intake systems. This aluminum component serves as the cap to your air filtration setup, controlling airflow dynamics and protecting your filter element from debris while maintaining engine bay cleanliness. Whether you're building a classic street rod, modern muscle car, or vintage restoration project, this X-Stream top delivers the aggressive styling that matches serious performance intent.

Constructed from lightweight aluminum and finished in black powder coat, the 9in X-Stream Filter Top combines durability with a refined appearance that complements any engine compartment aesthetic. The X-Stream design optimizes air entry patterns, reducing turbulence and promoting consistent filter saturation for improved airflow efficiency compared to stock lids. Measuring 12.1 x 2 x 12.5 inches and weighing just 1.11 lbs, this component integrates seamlessly into existing K AND N air cleaner assemblies, providing a direct bolt-on upgrade path. The black powder coat finish resists corrosion and UV fading, ensuring long-term durability in demanding under-hood environments.

Mechanics and engine builders favor the 9in X-Stream Filter Top for custom air intake projects where OEM lids lack visual impact or performance optimization. Installation is straightforward for anyone familiar with basic air cleaner assembly procedures, requiring only standard fasteners and no special tooling. This filter lid pairs with K AND N's round filter elements and base plates, making it an ideal choice for street machines, show vehicles, and track-focused builds seeking that competition-grade intake appearance combined with measurable airflow benefits.
