Product Details

The NGK 5599 Laser Iridium spark plug delivers premium performance and extended service life for demanding automotive applications. Featuring advanced iridium and platinum electrode technology, this spark plug is engineered to provide reliable ignition and superior durability.

Key Features:

  • Ultra-fine iridium center electrode provides superior ignitability and longer service life
  • Platinum-tipped ground electrode adds extra protection against wear and gap erosion
  • Original equipment specification on many late-model vehicles
  • Laser-welded iridium tip ensures precise spark location and maximum performance
  • Trivalent metal plating provides superior anti-corrosion and anti-seizing properties
  • Sold as a 4-pack for convenient multi-cylinder service

The combination of iridium at the center electrode and platinum at the ground electrode creates an optimized spark plug design that resists fouling, maintains proper gap spacing, and delivers consistent performance throughout its service life. The fine-wire iridium center electrode requires less voltage to fire while focusing spark energy for improved combustion efficiency.
