NGK, originating in Japan before World War II and developing throughout the Land of the Rising Sun’s modernization, today has facilities in West Virginia and Irvine, California too, where it makes high quality 2007-2017 engine parts for many vehicles, including the Sierra. Their 2007-2013 spark plugs include iridium variants, whose iridium tip practically guarantees toughness and a stable spark. The very high melting point of iridium means it can stand up to the heat generated by high performance, boosted engines, too. With these spark plugs in place, including NGK’s 2014-2017 spark plugs, you can count on getting improved acceleration and more fuel mileage from your GMC Sierra pickup. Corrosion of the plugs is delayed or prevented by trivalent metal plating, meaning you won’t need to change them often even under very harsh conditions.
