Spark reliably and burn cleaner with the NGK Laser Platinum Spark Plug 3586, a fine-wire platinum plug engineered specifically for OE applications that originally used a fine-wire platinum plug. It's designed to deliver high ignitability and longer service life than conventional nickel plugs, supporting stable idling, strong anti-fouling, and efficient combustion, and it's tested to NGK's quality and durability standards.
- Platinum-alloy fine-wire center electrode: longer wearing with higher temperature resistance than traditional nickel electrodes.
- Platinum-tip ground electrode: double-platinum metallurgy adds platinum protection at the ground electrode for even wear and service life.
- Solid 98% pure copper core: offers heat dissipation, conductivity, and a wide heat range; high-grade pure alumina ceramic insulator helps prevent overheating.
- Trivalent metal plating: anti-corrosion and anti-seize properties for easier installation and removal.
Resistor-type plug with about 1000 ohms of resistance to help suppress ignition noise. Pre-gapped to 0.044 in (1.1 mm), heat range 6, M14 x 1.25 thread, 0.750 in (19 mm) reach, J-gap ground, flat seat with an included crush washer. Country of origin: Japan. No vehicle fitment is listed for this part in our catalog — confirm the correct plug, gap, heat range, reach, and seat type for your engine before ordering.
