Toyota Iridium spark plugs, often branded by Denso or NGK, feature ultra-fine 0.4mm–0.7mm electrodes for superior ignitability, increased power, improved fuel efficiency, and long-lasting performance up to 100,000 km. Engineered specifically for Toyota engines (like 2AR-FE, 1NR/2NR), they are available in Long Life and Laser Iridium types, ensuring optimal combustion.
