The IE supercharger pulley for late 4 bolt style 3.0T V6 Audi engines extracts more power from your supercharger by spinning the unit 7% faster than stock, resulting in higher boost levels. Paired with a Stage 2 Tune, you can expect gains over 25 horsepower on pump fuel.
he IE 4 Bolt Style Supercharger Pulley is designed for many late-model Audi 3.0T Supercharged engines that use the non-press-fit updated bolt-on style of supercharger pulley found on many 2016+ B8/B8.5 S4, S5, Q5, SQ5, C7/C7.5 A6, A7, and Q7 models. The pulley functions by increasing the supercharger RPM throughout the full powerband. The IE pulley is 58.8mm in diameter, making it one of most aggressive and powerful on the market.
Does not fit early press-fit style S4, S5, A6 Q5/SQ5, and Q7. These engines are easily identified because the supercharger pulley has no bolts to attach it to the supercharger.
