What is the best spark plug for EA888 engines?

This is a common question among tuners. The internet is full of horror stories about broken electrodes, engine failures, and melted plugs at higher Stage levels. At Futurez, we have built a significant number of these engines in Finland. Based on collected real world data, we mainly use NGK SILFER8C7ES as well as Denso IKH24 and IKH01-24 plugs.

The Brisk ER12S is also a popular silver electrode option, but due to the softer material the service life is unfortunately shorter.

Denso is an excellent choice for most stock or tuned setups. If you need project specific help with your VAG engine, you can easily contact our specialists for example via WhatsApp through our contact page.

For spark plug gap, we recommend using the factory default gap or approximately 0.6 mm in tuned engines.
