NGK PFR6T-G Laser Platinum Spark Plug – Stock No. 6314
This NGK Laser Platinum spark plug is built for consistent ignition, long life, and stable performance. The fine platinum centre electrode needs less voltage to fire, which helps cold starts and smooth running. A platinum pad on the ground electrode improves durability, keeping the gap stable for longer service intervals.
Use it as a like-for-like replacement where PFR6T-G is specified, or as a quality upgrade over standard copper plugs. It suits daily use and tuned petrol engines that need a reliable spark under load.
- Sharper spark with less misfire under boost and high RPM
- Improved throttle response and smoother idle
- Long service life thanks to dual precious metals
Always check your vehicle’s required heat range and plug type before fitting. Use our vehicle lookup or see the Vehicle Fitment tab to confirm compatibility.
