What spark plugs does Toyota recommend?

Written by Editorial Team | Last Updated: August 2026

Toyota vehicles are typically engineered to perform best with original equipment manufacturer (OEM) spark plugs supplied by trusted industry leaders such as Denso and NGK. Depending on the specific model, engine configuration, and year of manufacture, Toyota factory specifications usually call for high-durability iridium or double-platinum spark plugs designed to ensure optimal fuel combustion, smooth idling, and long service intervals. Checking the vehicle owner manual or the under-hood emission control information label ensures you install the precise heat range and gap required for your exact engine.
