Overview
NGK builds this traditional spark plug with a copper core, a ceramic top and a resistor made from a glass and carbon mixture. A triple gasket sealing process and cold rolled threads are included in the design.
The insulator is made of pure alumina silicate with a long nose, and corrugated ribs help avoid flashover. The listing gives the thread size but not the gap, reach or the vehicle list, only a cross reference of replaced numbers.
Who it's for
For routine tune-ups on engines that specify this plug code, sold here as a single plug. Owners with a different heat range or thread need a different NGK number.
Pros and cons
- Copper core conducts heat
- Resistor of glass and carbon mixture
- Triple gasket seal against leakage
- Corrugated ribs avoid flashover
- Gap and reach not listed
- Vehicle fitment is by cross reference
- Sold singly, not a set
Performance notes
A copper core carries heat from the tip, and the ceramic insulator with corrugated ribs resists flashover. The triple gasket seal is designed to prevent fuel leakage and cold rolled threads help protect the cylinder head.
