NGK PFR6H-10 Platinum Spark Plug (Stock No. 6290)
The NGK PFR6H-10 is a long-life platinum spark plug designed for clean ignition, stable idle, and reliable performance. It uses a fine platinum centre electrode to improve spark efficiency and reduce misfires, especially under load. The resistor design helps cut electrical noise that can affect sensors and the ECU.
Platinum construction offers longer service intervals than standard copper plugs. It also holds its gap better over time, which helps maintain throttle response and fuel economy.
