9in x 5in Air Cleaner Assembly

The 9in x 5in Air Cleaner Assembly is an essential upgrade for automotive enthusiasts looking to optimize engine induction while maintaining a timeless aesthetic on their performance builds. Designed specifically for carbureted applications, this assembly provides the necessary surface area to ensure your engine breathes freely during high-load scenarios. Whether you are finishing a classic muscle car restoration or fine-tuning a custom street rod, this kit offers the perfect balance of filtration efficiency and engine bay styling.

Built with a focus on durability and airflow, this 9-inch round unit features a 6.375-inch height and a raised base to accommodate various throttle linkage configurations. The 5-1/8 inch carburetor flange is a standard fitment for most popular four-barrel carburetors, ensuring a secure and leak-free seal on the intake neck. The assembly is constructed from high-quality stainless steel with a polished finish, featuring the iconic K&N logo embossed on the top plate for a professional, race-ready look under the hood.

This comprehensive kit is ideal for drivers who demand the longevity of a washable filter media combined with the structural integrity of a heavy-duty housing. Because of the 6.375-inch height, you should verify hood clearance before installation to ensure the assembly does not interfere with the vehicle's bodywork. The polished stainless steel finish not only resists corrosion but also simplifies maintenance, making the 9in x 5in Air Cleaner Assembly a reliable choice for long-term engine protection and consistent performance.
