HMS 14" Racing Air Cleaner Deluxe Kit
The HMS 14" Racing Air Cleaner Deluxe Kit is designed to provide dependable airflow and protection in demanding racing conditions. The aluminum air-cleaner base uses a double O-ring sealing system to help prevent dirt and debris from reaching the carburetor and engine.
Kit Includes:
- 1 – HMS 14" aluminum air-cleaner base with double O-ring seal
- 1 – HMS 14" aluminum air-cleaner lid
- 1 – Hammond Motorsports washable 4" × 14" air-filter element—no oil required
- 1 – Complete air-cleaner stud kit
- 1 – Outerwears pre-filter
- 1 – Black Outerwears scrub bag
Color Options:
Choose black, blue, red, white, or mill finish for the air-cleaner lid and base.
Choose black, blue, red, yellow, orange, or purple for the Outerwears pre-filter.
The scrub bag is available in black only.
Stud Kit Fitment:
Choose either the 1/4" or 5/16" stud option.
The included stud kit fits Holley 4412 and most 4-barrel carburetors. It does not fit the Holley XP 4412 carburetor.
If no different colors are selected, the air-cleaner lid, base, and pre-filter will be supplied in black.
The Hammond Motorsports filter fits tightly between the air-cleaner base and lid to help prevent dirt from bypassing the filter and entering the carburetor. The washable filter element requires no oil, eliminating the mess and problems caused by applying too much, too little, or uneven filter oil. Over-oiling can restrict airflow and affect filter performance. Combined with the double O-ring sealing system, this design helps keep the carburetor and engine cleaner, maintain consistent engine performance, and reduce dirt-related engine wear for longer engine life.

Air Cleaner kit
This air cleaner kit will eliminate dirt getting into your engine from flimsy units sold for dirt track racing. Fine dirt will wear out your engine very quick and engines cost alot of money. We tried different products, grease ,etc and we still saw that dirty film in the carb after a race. This is our second base kit and thats all I will ever use again--problem solved.
