NGK PZFR6F Laser Platinum Spark Plug (Stock No. 7550)
This NGK Laser Platinum plug delivers a clean, consistent spark for reliable starts and smooth running. The fine platinum centre fires easily, helping combustion at idle and under load. A platinum pad on the ground electrode resists wear, so the gap stays stable for longer service life.
It is a good choice for standard or lightly tuned petrol engines where long life and steady ignition performance matter. Expect crisp throttle response, stable idle, and dependable cold starts without fuss.
