Check the part number on your existing cap or consult your owner's manual. Most caps are compatible with specific engine brands like Briggs & Stratton, Honda, or Kohler, so matching the engine model is crucial for a proper seal.
Aftermarket caps often provide better value and are widely available. High-quality aftermarket options like those from XYQMLY or FLYPIG offer comparable durability and fit to OEM parts, often at a lower price point.
