NGK Laser Iridium Spark Plug Box of 4 (ILKAR7L11/04) for Select Mazda, Toyota, and Scion 2012-2020

Fits select 2012-2020 Mazda 3, 6, CX-3, CX-30, CX-5, and MX-5 Miata, 2016 Scion iA, and 2017-2020 Toyota Yaris / Yaris iA.

NGK Laser Iridium spark plugs are engineered for drivers seeking long-service life and consistent ignition performance. As a precise OE replacement, these plugs feature a laser-welded fine-wire iridium center electrode and a platinum pad on the ground electrode. This combination provides exceptional resistance to spark erosion and ensures even wear, specifically in modern distributorless ignition systems where electrode longevity is critical.

The construction utilizes a high-grade pure alumina silicate ceramic insulator for superior dielectric strength and thermal conductivity. A 98 percent pure copper core facilitates rapid heat dissipation to prevent pre-ignition and overheating. The trivalent metal plating offers robust anti-corrosion and anti-seizing properties, making future plug changes easier by preventing the threads from bonding to the cylinder head.
