Yttrium center electrode with copper core and U-groove ground electrode

Service life of up to 40,000km

Durable

Fuel efficient

Smoother combustion

• 2 ground electrodes increase durability

• Increases Engine Performance and Throttle Response, U-Groove ground electrode design gives the flame a groove to grow in, resulting in less flame dissipation and a larger flame front for a more complete combustion. This translates to better fuel efficiency and improved throttle response.
