Installation Notes and Tips

Verify thread diameter, reach, seat type, terminal style, and heat range before installation. The pre-gap is listed at 0.028, but final gap should always be checked against the engine manufacturer’s specification for the exact application. Use proper torque procedures and inspect the ignition lead or cap for wear before installing the new plug.
