Product Details

• The Briggs & Stratton 272490S Pre Cleaner is a genuine OEM pre-filter that protects the engine’s main air filtration system by pre-trapping larger airborne debris before it reaches the primary filter.
• Constructed with durable foam media and an engineered pore structure, the pre-cleaner resists tearing and remains effective through repeat cleaning and outdoor exposure.
• Its OEM-matched dimensions and slip-on design ensure a secure fit over compatible air filter housings, helping reduce service frequency and maintain reliable air intake protection.
• Key benefits include extending the life of the main air filter, sustaining optimal airflow, and supporting consistent engine performance in dusty, dry, or debris-rich environments typical of mowing, landscaping and ground preparation tasks.
• Part Reference: 272490S confirms the correct Briggs & Stratton replacement part number. This pre-cleaner replaces or supersedes related references when listed in parts catalogs (e.g., 272490, 792490, 799490). Always confirm fitment against your engine’s illustrated parts list and Model–Type–Code.

Compatibility

• Used on select Briggs & Stratton engines and outdoor power equipment where an external pre-filter is specified by the original parts diagram. Typically found on walk-behind lawn mowers, garden tractors and other small machines that operate in dusty or debris-rich conditions.
• Engines with external pre-filter mounting provisions (pre-filter boss) or slip-on air intake cover design.
• Typical compatible families include horizontal-shaft OHV single-cylinder engines used on push mowers and small garden equipment; exact fitment depends on Model–Type–Code—verify with your parts manual.
