NGK Laser Iridium Spark Plug Box of 4 (ILKAR7B11) - Select Toyota, Lexus, Scion, Pontiac 2008-2015

Fits select 2008-2015 Lexus CT200h, Pontiac Vibe, Scion iQ/xD, and Toyota Corolla, Matrix, and Prius models.

NGK Laser Iridium spark plugs are engineered as the ultimate OE-replacement solution, combining a fine-wire iridium-tipped center electrode with a platinum pad on the ground electrode. This hybrid precious metal design ensures maximum service life and consistent spark throughput in modern distributorless ignition systems. The 0.6mm laser-welded iridium tip provides high durability and a focused spark for improved ignitability and throttle response.

Each plug features a 98% pure copper core for superior heat dissipation, preventing pre-ignition and fouling under high-load conditions. The trivalent metal plating offers high-grade anti-corrosion and anti-seizing properties, ensuring the plugs can be safely removed even after extended service intervals.
