Integrated Engineering Product Description
The 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.
