- Pure alumina silicate ceramic insulator provides superior strength and better heat transfer
- Trivalent metal plating for superior anti-corrosion and anti-seizing properties
- RECOMMENDED USAGE: Best for vehicles with OE fine wire iridium alloy plugs
- Copper core aids in heat removal
- Triple seals prevent leakage
The NGK Laser Iridium Spark Plug (Part Number 4996) offers an optimal balance of performance and longevity, specifically engineered for OE applications across a variety of vehicles. Featuring an iridium-tipped center electrode, this spark plug provides six times the durability of platinum, ensuring consistent and reliable ignition over extended periods. The high-grade pure alumina ceramic insulator delivers superior strength and efficient heat transfer, protecting the spark plug from overheating and maintaining optimal engine performance. Its copper core enhances heat removal, contributing to stable operation and efficient combustion. Most Laser Iridium plugs include a platinum pad on the ground electrode, promoting even wear and extending service life, especially in distributorless ignition systems. Designed to meet or exceed OE standards, these spark plugs are tested rigorously to uphold quality and durability in demanding automotive environments. They are ideal for vehicles equipped with OE fine wire iridium alloy plugs, ensuring seamless compatibility and optimal engine function. This set of four is compatible with multiple vehicle models, including various Toyota, Saturn, Geo, and Pontiac models from the early 1990s through the mid-2010s. Engineered with triple seals to prevent leakage and corrosion, NGK's Laser Iridium plugs are a reliable choice for drivers seeking improved ignition performance and longevity. Whether for replacement or upgrade, these spark plugs deliver consistent sparks for smooth engine operation and enhanced fuel efficiency in compatible vehicles.
