Installation Notes
- Ensure the engine is cool to the touch before starting.
- Disconnect the negative terminal from the battery for safety.
- Clean the area around the spark plug to prevent debris from falling into the cylinder.
- Disconnect the spark plug wire or ignition coil.
- Using a spark plug socket and ratchet, turn the old plug counter-clockwise to remove it.
- Verify the gap on the new spark plug and adjust if needed for your specific engine.
- Thread the new spark plug into the cylinder head by hand to avoid cross-threading.
- Once finger-tight, use a torque wrench to tighten the plug to the manufacturer's specification. If no torque spec is available, tighten 1/4 to 1/2 turn past finger-tight.
- Reconnect the spark plug wire or ignition coil.
- Reconnect the battery terminal.
Troubleshooting & FAQ
How do I confirm this fits my engine?
This plug fits a wide variety of Honda, Suzuki, Yamaha, Arctic Cat, and other models. The best method is to confirm your model and year in the compatibility table above. For 100% certainty, cross-reference the part number with your vehicle's service manual.
What is the correct spark plug gap?
The plug is pre-gapped at 0.9mm (0.035 inches), which is suitable for most listed applications. However, always consult your owner’s manual for the precise gap specification and adjust with a gapping tool if necessary.
How often should I replace this spark plug?
The recommended service life is up to 30,000 miles under normal operating conditions. Shorter intervals may be necessary for engines under heavy load, using lower-quality fuel, or showing signs of poor performance.
What are the signs of a failing spark plug?
Common symptoms include rough idling, engine misfires, poor acceleration, reduced fuel efficiency, and difficulty starting. A visual inspection may reveal black (carbon-fouled), wet (oil-fouled), or white (burnt) deposits on the electrode.
