NGK PFR6Q Laser Platinum Spark Plug – Stock 6458
The NGK PFR6Q is a premium Laser Platinum spark plug designed for consistent ignition and long service life. It delivers a strong spark, stable idle, and reliable performance under load. The fine platinum centre electrode lowers the voltage needed to fire, which helps cold starts and reduces misfires. A platinum ground pad improves durability and keeps the gap stable over time.
This plug suits tuned and standard engines alike, offering clean combustion and good fuel efficiency when installed and gapped correctly.
- Precise, stable spark for smoother running
- Platinum firing surfaces for long life and consistent gap
