Torque Solution Underdrive Crank Pulley Kit Porsche Boxster/Cayman/996/997 w/AC (Excl Turbo Engines)

Torque Solution is known for making well-built engine and drivetrain components for performance applications. This underdrive crank pulley kit is designed specifically for your 1998-2013 Porsche 911, including Boxster, Cayman, and 996/997 models equipped with air conditioning, but it will not fit turbo engines. By slightly slowing down accessories like the alternator and AC compressor, this pulley can free up a small amount of horsepower that would otherwise be used to drive them.

This kit is made from strong aluminum, which helps keep the overall weight down. The underdrive design means the accessories spin a bit slower than stock, which can lead to a more comfortable interior temperature if your AC system is working hard, and it can also reduce the load on the alternator. It's a straightforward swap for the factory pulley, making it a popular choice for owners looking to get a little more out of their engine without major modifications.
