The NGK Laser Iridium spark plug combines a fine iridium center electrode with advanced tip technology to provide high ignitability and long service life for OE-equivalent replacement. High-grade alumina ceramic and a 98% copper core help manage heat and support reliable starts. Raised platinum pads or fine-wire tips on the ground electrode promote even wear; trivalent plating and triple seals resist corrosion and leakage.
