Ready to add some serious horsepower to your 12-18 Audi A6/A7, 13-18 A8, 13-17 Q5/SQ5, 10-17 S4/S5? The 034Motorsport 207mm Crank Pulley Upgrade 034-145-Z053 is an easy way to increase power by increasing the supercharger rotational speed resulting in more boost to your engine. This works with the OEM supercharger pulley to create the proper dual pulley ratio which is required for 034's Stage 2+ tuning software.

The 034Motorsport 3.0 TFSI Supercharger 207mm Crank Pulley Upgrade is machined from a single piece of 6061-T6 billet aluminum, and anodized black for an attractive finish resistant to corrosion. This design is 60% lighter than the OE pulley, significantly reducing rotational weight and parasitic loss. This is a single-piece inner and outer pulley, not a pulley "overlay", which adds rotational weight.

WHAT’S INCLUDED:

• 034Motorsport 3.0 TFSI 207mm Crank Pulley
• Continental 1370mm Crank Pulley V-Belt
• M8x1.25x25mm Class 12.9 Zinc Coated Socket Head Cap Screws (qty 8)

NOTE: Performance software is sold separately and is required in order to use this pulley safely and for this pulley to yield a performance benefit.
