The Green Spark Plug Company

The NGK CR7HSA-9 is part of the NGK Standard range.A conventional NGK nickel-alloy spark plug with a copper-cored centre electrode. The copper core carries heat away from the firing tip quickly, which lets the plug run cooler under load while still burning off deposits at low speed, so it resists both overheating and fouling better than a plain nickel plug. NGK's standard range is the direct replacement where a conventional plug is specified and remains the sensible choice for classic engines, motorcycles, garden machinery and everyday servicing. Easy to inspect and re-gap, with a triple-seal construction against gas leakage and a corrugated insulator to prevent flashover.
