14in X-Stream Flow Top Polished

The K AND N ENGINEERING 14in X-Stream Flow Top Polished air cleaner lid is purpose-built for serious engine builders and performance enthusiasts who understand that unrestricted airflow directly translates to measurable horsepower gains. This aluminum assembly replaces restrictive OEM air filter covers, enabling your intake system to breathe more efficiently while maintaining a clean, finished appearance under the hood. Whether you're building a street machine, weekend track car, or high-output engine combination, this top lid is an essential component for maximizing cold air delivery to your fuel injection or carburetor system.

Constructed from premium polished aluminum, the 14 inch diameter X-Stream Flow top features an optimized internal geometry that promotes laminar airflow while reducing turbulence and pressure drop across the filter element. The X-Stream Flow design incorporates K AND N's proven engineering principles—expanding internal passages and strategic internal baffles that encourage smooth, unrestricted air movement into the engine. At just 2.15 pounds, this lightweight assembly minimizes rotating mass while the durable polished finish resists corrosion and maintains its showroom appearance through years of hard use, making it as functional as it is visually compelling.

Mechanics and engine builders working on 14 inch round air filter applications will find this top compatible with both carbureted and fuel-injected platforms, making it ideal for hot rod engines, LS swaps, vintage restorations, and modern performance builds. Installation is straightforward—it securely seats atop your existing K AND N filter element or compatible round air filter base, requiring no special tools or modifications. The polished finish makes this component a focal point when engine bay dress-up matters, while the superior X-Stream Flow engineering ensures that every cubic inch of your engine receives maximum, unrestricted airflow for peak combustion efficiency.
