Setup, Compatibility & Care
To ensure proper function, verify your vehicle’s service manual for the correct heat range and plug type before installation.
- Preparation: Always ensure the engine is cool to the touch before removing old plugs to prevent damage to the cylinder head threads.
- Installation: Hand-thread the new plug to avoid cross-threading, then use a torque wrench to tighten to the manufacturer's specified foot-pounds.
- Compatibility: While this plug replaces various OE numbers (such as NIS-2240101P16 and HON-9807956147), verify the specific engine requirements for your model year as multiple options may exist.
- Care: Inspect plugs every 15,000 to 30,000 miles, checking for carbon buildup or electrode erosion to maintain peak efficiency.
