Installation Notes and Tips

Verify engine code and VIN against the fitment list before installation. Confirm the specified 0.028 in gap and inspect the plug wells, coil boots, and threads before fitting the new plug. Use the correct torque procedure for the aluminum cylinder head and avoid over-tightening. This plug is listed for N/A position applications only, so match it to the exact engine specification shown for your vehicle.
