Stage 1 & 2 Volkswagen GTI & Golf R MkVII.

Upgrades - These plugs are one step colder versus OEM - one step colder is typically recommended for Stage 2 tunes and higher:

Audi C7 S6/S7/RS7 4.0t Stock Replacement.

Fires properly even if partially fouled, where standard plugs will fail.

Reduces stress and wear on your coil and other ignition components.

Low ignition voltage requirements (easier for spark to jump over).

1.5 mm Silver Fine Wire Center Electrode.

Good Resistance to Fouling and Easier Starts.

Lower Required Supplied Ignition Voltage.Cooler heat range for some applications allowing detonation resistance in high power applications.Superior Ignition Ability Increases Engine Power allowing detonation resistance in high power applications.Silver spark plug electrodes transfer electricity & heat better than any other spark plug material resulting in consistent peak spark performance required to propagate efficient combustion! This is beneficial for a full complete combustion of the available fuel and air in the combustion chamber, combustion efficiency creates horsepower gains.

These long-life silver spark plugs will outperform the factory spark plugs and are a recommended performance upgrade for the Volkswagen & Audi EA888 Gen 3 ignition system, as well as other high performance Audi and VW setups. The Brisk Racing ER12S spark plugs are ideal for cars with performance software upgrades and/or turbocharger upgrade kits running increased boost pressure.
