CTS B8/B8.5 Audi A4/A5/AllRoad 1.8T/2.0T TFSI Lightweight Crank Pulley Kit

The CTS Turbo lightweight crank pulley kit replaces the factory crankshaft pulley on B8 and B8.5 Audi A4, A5 and AllRoad models equipped with 1.8T or 2.0T TFSI engines. Precision-machined from aircraft-grade aluminium, this pulley significantly reduces rotating mass at the crankshaft, allowing the engine to spin up more freely. The result is improved throttle response, faster rev transitions and reduced parasitic drag on the drivetrain. Complete kit includes the pulley and necessary hardware for straightforward installation. Compatible with both manual and automatic transmissions across the 2009-2017 model range.
