HMS 14" Air Cleaner Lid – Precision CNC-Spun Construction

Every Hammond Motorsports (HMS) air cleaner lid is precision CNC spun to exact specifications for exceptional fit, strength, and consistency. Manufactured from a high-strength hardened aluminum alloy, our lids are engineered to withstand the demanding conditions of dirt track and high-performance racing.

Each lid features a 1/2-inch-tall outer retaining lip that securely supports the air filter element, helping keep it properly centered and clamped during high vibration and extreme racing conditions.

Why Strength Matters

A stronger air cleaner assembly does more than improve durability—it helps maintain proper filter support and contributes to cleaner airflow.

A rigid HMS air cleaner lid helps:

Maintain even clamping pressure on the air filter element
Reduce flexing under engine vibration and racing conditions
Help minimize the chance of unfiltered air bypassing the filter
Promote smooth, consistent airflow into the carburetor
Help protect expensive engine components from abrasive dirt contamination
Contribute to more consistent engine performance and longer engine life

When an air cleaner lid flexes, the filter element may not remain evenly compressed against the lid. Over time, this can reduce sealing effectiveness and allow dirt to bypass the filter. That's why Hammond Motorsports builds every air cleaner lid for racers who demand maximum durability, consistent sealing, and dependable performance.

Built for Serious Racers

The HMS 14-Inch Air Cleaner Lid is engineered for racers who refuse to compromise on quality. Precision CNC spinning and premium hardened aluminum alloy combine to produce one of the strongest air cleaner lids available for racing applications.
