Genuine Toyota/Lexus Iridium Spark Plug (90919-01275 / SC16HR11)

The 90919-01275 is a premium Original Equipment Manufacturer (OEM) spark plug, manufactured by DENSO (model SC16HR11) specifically for Toyota and Lexus vehicles. Utilizing Iridium technology, this plug offers a much higher melting point than standard platinum or copper plugs, allowing for a thinner electrode design. This results in a more concentrated spark, better throttle response, and reduced emissions.
