Installation Notes

Verify engine style before ordering, especially for 2008 applications that require the brown coil boot configuration. Confirm the specified 0.044 in gap before installation and follow the vehicle service procedure for torque and coil-on-plug removal. Check the existing plug condition for signs of oil fouling, carbon buildup, or electrode wear when diagnosing ignition issues.
