• Stops airborne debris from contaminating internal components.
• Maintains proper air-to-fuel mix for smoother idling and start-up.

What should I check before installing the MaBoltx filter and cover?

Measure and inspect your current filter and housing to ensure the MaBoltx kit matches the size and attachment points. Confirm that the engine model and mower part number correspond to the compatibility list. If unsure, compare the OEM part number stamped on your original filter or consult the mower manual.

• Compare part numbers: Tecumseh 36905 / Craftsman 33331 / Stens 100-812 replacements.
• Check the filter housing shape, bolt or clip locations, and overall dimensions.
• Replace during routine tune-ups or if the old filter shows heavy soiling or damage.
