NGK PFR6J-11 Laser Platinum Spark Plug – Stock 2743
This NGK Laser Platinum plug delivers a strong, clean spark for reliable starts and smooth running. The fine-wire platinum centre helps ignite the mix quicker and needs less voltage. That can reduce misfires, aid fuel economy, and keep performance consistent over a long service life.
It is pre-gapped to 1.1 mm and uses a resistor to cut radio noise. The projected tip helps stable combustion under part and full load. Built for long intervals compared to standard copper plugs.
- Strong spark and stable idle
- Long service life from dual platinum design
- Pre-gapped for easy installation
