NGK Laser Platinum spark plugs provide reliable ignitability and extended service life compared with standard nickel plugs through laser-welded platinum surfaces. As OE-equivalent replacements they pair high-grade alumina ceramic insulation with a 98% copper core to control heat and support consistent starts. Platinum ground pads help slow wear for improved idle stability, anti-fouling, and modest fuel efficiency benefits.
