NGK PZFR6J-11 Spark Plug – Stock No. 3586
This NGK spark plug uses a fine platinum centre electrode for stable ignition and long life. It is designed to improve cold starts, reduce misfires, and keep performance consistent over more miles. The projected-tip layout helps place the spark in the heart of the mixture for clean, efficient burn.
It comes factory gapped at 1.1 mm (-11). This suits many modern petrol engines that specify an NGK heat range 6 plug with a projected tip. Use the site’s vehicle lookup to confirm exact fitment, or check the Vehicle Fitment tab.
- Strong spark with low voltage demand for reliable starting
- Platinum centre and ground pad for slow wear and steady performance
- Resistor type to control electrical noise for the ECU and infotainment
