- 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
Experience enhanced engine performance and longevity with the NGK Laser Iridium Spark Plug, part number 1637. Engineered specifically for OE applications, these spark plugs deliver reliable ignition and superior durability. The iridium-tipped center electrode is six times harder than platinum, providing longer service life and consistent spark quality. Crafted with high-grade pure alumina ceramic and a 98 percent pure copper core, these plugs effectively prevent overheating and ensure reliable starts in demanding engine conditions. This combination of materials optimizes heat transfer and insulates the ignition system against thermal stress, making them ideal for modern vehicle requirements.
These spark plugs feature a platinum pad on the ground electrode for even wear, especially suited for distributorless ignition systems. The trivalent metal plating enhances corrosion resistance and reduces seizing, simplifying installation and maintenance. Designed for vehicles such as Hyundai Santa Fe (2009 model) and Kia Optima (2010-2011), they are perfect replacements for OE fine wire iridium plugs, ensuring compatibility and peak performance.
Each box contains four NGK Laser Iridium Spark Plugs, making them suitable for complete ignition system upgrades. Their triple seals prevent leakage, maintaining consistent performance over time. Whether you're aiming for improved fuel efficiency, smoother acceleration, or reliable cold starts, these spark plugs provide a dependable solution for your vehicle's ignition needs.
