The primary difference between the AYFS32YR and AYFS22FM spark plugs lies in their specifications and applications. The AYFS32YR typically features a different heat range and design suited for specific engine performance needs, while the AYFS22FM may cater to a different engine type or operational conditions. Additionally, variations in electrode design, material, and gap size can affect ignition and combustion efficiency. Always refer to the manufacturer's recommendations for the appropriate spark plug for your vehicle.
