Product Description: The Brisk Racing ER12S spark plugs are ideal for cars with performance software upgrades and/or turbocharger upgrade kits running increased boost pressure. 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. 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. Replaces Part Number: 06K 905 601 D 06K 905 601 M Features: Superior Ignition Ability Increases Engine Power allowing detonation resistance in high power applications Cooler heat range for some applications allowing detonation resistance in high power applications Lower Required Supplied Ignition Voltage Good Resistance to Fouling and Easier Starts 1.5 mm Silver Fine Wire Center Electrode Low ignition voltage requirements (easier for spark to jump over) Reduces stress and wear on your coil and other ignition components Fires properly even if partially fouled, where standard plugs will fail Specifications: Thread Size: 14mm Reach: 26.5mm-1in Hex Size: 16mm-5/8in Seat Type: Gasket Design: Silver Center Electrode Resistor: Yes Projected: No Applications: OEM+ Replacement Audi C7 S6/S7/RS7 4.0t Stock Replacement Stock Audi 8S TTRS & 8V.5 RS3 2.5 TFSI Stock Audi 8J TTRS 2.5T Upgrades - These plugs are one step colder versus OEM - one step colder is typically recommended for Stage 2 tunes and higher: Stage 1 & 2 Volkswagen GTI & Golf R MkVII Stage 1 & 2 Volkswagen Alltrack EA888.3 1.8T Stage 1 & 2 Audi 8S TT/TTS 2.0t Stage 1 & 2 Audi 8V/8V.5 A3/S3 Stage 1 & 2 Audi B9 A4 2.0t NOTE: Apply a thin coating of high temperature anti-seize to the threads prior to installation to avoid corrosion on the threads of the spark plug and/or head.
