Upgrade crankshaft pully kit for all 2.0L TFSI EA113 engines with belt driven. The Upgrade crank pulley is lightened to reduce parasitic drag on the engine. This results in faster revving and more horsepower. The crankshaft pulley is made from high quality aluminum and hard anodized for durability. Unlike color anodizing which is mostly cosmetic, hard anodizing builds up a hardened layer over the base material to help prevent wear Included in the Kit: Upgrade Crank Pulley New Belt New Bolts Fits for engines: 2.0L TFSI EA113 engines with belt driven for example engine codes: AXX, BHZ.
