Product Description:
The Brisk Racing 2MOR10S spark plugs are high performance spark plugs that 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 Audi B9 S4, S5, RS5, & SQ5 powered by the EA839 engine, as well as other high performance BMW 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.
