9009866011 Spark plug NGK 4623 M12 x 1,25 18 mm

The NGK DR5HS 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.

High-grade alumina silicate ceramic insulator for superior strength and heat transfer Cold-rolled threads to prevent cross-threading and damage to cylinder heads Trivalent plating eliminates need for anti-seize and corrugated ribs prevent flashover Quantity: 1 per package International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions.
