Why choose this plug
It holds a stable spark under boost and high RPM. The platinum tips resist wear, so the gap stays correct for longer. This helps throttle response, fuel economy, and smooth running over a long service life.
Installation notes: Fit to a cold engine. Do not use anti-seize. Tighten to the specified torque. If checking the gap, use a wire gauge and avoid bending the fine electrodes.
