Product Details

The NGK 91360 (MR8BI-8) Laser Iridium spark plug is a resistor-type iridium spark plug built for long service life, stable idle and dependable ignition. It uses a laser-welded fine-wire iridium center electrode and a platinum-tipped ground electrode. NGK designs these plugs for OE applications, so this ignition plug works as an OE-equivalent replacement or a performance-minded upgrade.

Key Features:

  • 0.6mm fine-wire iridium center electrode for high ignitability, durability and a consistently stable spark
  • Platinum-tipped ground electrode for slow wear, anti-fouling performance and lower emissions
  • Trivalent metal plating for anti-corrosion and anti-seizing properties, which makes installation and removal easier
  • Pure alumina silicate ceramic insulator for strength and better heat transfer
  • Copper core to help draw heat away from the tip
  • Corrugated ribs to help prevent flashover, plus triple seals to prevent leakage

Specifications:

  • NGK part number: 91360; model: MR8BI-8
  • Thread size: 10mm, 1.0mm pitch
  • Reach: 19mm (3/4 in.)
  • Hex size: 5/8 in. (16mm)
  • Seat type: gasket
  • Heat range: 8
  • Resistor: yes, 5k ohm
  • Terminal: solid, non-removable
  • Center electrode projection: non-projected
