Air Cleaner 4in x 2in Kit

The SPECTRE Air Cleaner 4in x 2in Kit (SPE4790) is a precision engine intake filtration assembly designed for small-displacement engines commonly found in portable generators, compressors, and lightweight tactical support equipment. Field-tested in demanding operational environments, this air cleaner kit delivers reliable protection against dust, debris, and particulate contamination—critical factors when equipment reliability directly impacts mission success. Built to military-grade standards, the assembly ensures consistent airflow and engine longevity in remote, austere conditions where resupply is limited and downtime is unacceptable.

The kit features a 4-inch round air cleaner housing with a 2-inch replacement filter element, compatible with carburetors using either 2-5/8 or 2-5/16 inch flanges and raised-base mounting configurations. Constructed from steel with a durable chrome finish, the assembly resists corrosion and harsh environmental exposure while maintaining structural integrity under thermal cycling and vibration stress. The two-piece design—housing and replaceable element—allows field technicians to perform quick maintenance without specialized tools, extending service intervals and reducing logistics burden in forward-deployed settings.

This air cleaner assembly is ideal for personnel maintaining small engines in tactical, military, and emergency response applications where equipment uptime and portability are paramount. The compact 4.8 x 3.05 x 6 inch footprint and lightweight 0.569 lb design minimize vehicle weight penalties while maximizing intake protection. Technicians should verify flange diameter and mounting base configuration before installation; the raised-base design ensures proper hood clearance on enclosed equipment and prevents accidental displacement during transport or field operations.
