Setup, Compatibility & Care
Before installation, always disconnect the spark plug wire to ensure safety. Remove the old spark plug using a deep-well socket. Before threading in the Torch Takumi BMR4A, consult your equipment’s owner manual to confirm the factory-recommended electrode gap. Use a feeler gauge to adjust the gap as necessary. Hand-thread the new plug to prevent cross-threading the cylinder head, then tighten to the manufacturer's specified torque. To maintain the plug, visually inspect it every 25 to 50 hours of operation for signs of oil fouling or excessive carbon buildup, and clean or replace it if the electrode shows significant erosion.
