Air Cleaner Assembly Dominator 4500 14x4

The K&N Air Cleaner Assembly Dominator 4500 14x4 is a custom high-flow induction system engineered for carburetor-equipped engines seeking maximum air intake velocity and filtering efficiency. Built for enthusiasts and engine builders who demand performance alongside reliability, this 14-inch round assembly replaces restrictive OEM air cleaners with a washable, reusable design that reduces intake restriction while maintaining superior dirt separation. The Dominator platform has earned respect across street rods, classic muscle cars, and custom engine builds where airflow directly translates to horsepower gain.

This assembly features a 14-inch diameter housing with a 5.5-inch height profile and a 7-5/16-inch carburetor flange, designed to fit a wide range of four-barrel and two-barrel carb configurations with proper adapter selection. The raised base allows clearance for carburetor linkage and fuel lines, critical for vehicles with tight engine compartment layouts. Construction combines chrome-finished steel components with K&N's signature molded design, delivering both durability and show-quality aesthetics. The washable filter element—a K&N trademark—eliminates disposable filter waste and provides consistent airflow over thousands of miles, with recharge service available commercially or at home.

Installation suits carbureted engines from 327 cubic inches to 454 big-blocks, provided your carburetor bolt pattern and intake manifold layout accommodate the 7-5/16-inch flange diameter. Weighing 5.63 pounds, the compact 14 x 6.4 x 14-inch profile fits most under-hood spaces without requiring custom fabrication. Mechanics and fabricators rely on this assembly for restorations, hot rods, and performance upgrades where OEM air cleaners create measurable intake restriction and appearance limitations. Pair with a compatible intake manifold adapter and fuel line routing plan for seamless fitment on your specific platform.
