IE 207mm Dual Pulley Ratio Crank Pulley & Damper Kit

The Integrated Engineering IEBAVJ6 is a 207mm dual pulley ratio crank pulley and damper upgrade kit engineered for Audi's 3.0T TFSI engines. This upgrade replaces the factory crank pulley and engine damper to increase supercharger RPM by a significant 27.6% over stock, leading to higher boost levels and improved performance. This kit is designed for direct fitment on various Audi models including the B8/B8.5 S4, S5, Q5, SQ5, and C7 A6, A7. It is crucial to note that the 2016-2018 Audi A6 and A7 models with CREC 3.0T engines do not have compatible IE software support for the 207mm lower crank pulley. For these specific models, IE offers single pulley CREC tunes that operate safely. To achieve the full performance potential and ensure proper operation, this crank pulley upgrade requires additional components. These include the IE POWERlink OBD tool and an ECU tune. For DSG transmission equipped vehicles, a specific DSG transmission tune is also necessary. Professional installation is recommended for this component.
