034Motorsport is pleased to offer this Upgraded External Wastegate Diaphragm for Early Audi I5 10V/20V Turbo Engines, including the MC, 3B, AAN, ABY, and ADU. We carried the factory replacement diaphragm for 10 years before Audi decided to discontinue it. In that time, our engineers had the opportunity to develop and test a stronger, more durable replacement. The result is this polyester reinforced, high-temperature silicone diaphragm, which is over 50% thicker than the factory unit and capable of performing in high-temperature, high-boost applications. Replaces factory part number 035145797B.

This performance polyurethane snub mount fits most Audi vehicles manufactured through 2001, and is designed to increase stabilization of the motor under acceleration. Our polyurethane snub mount is a direct replacement for the stock snub mount, and offers much longer life and drastically improved performance by reducing unwanted engine movement.
