VW 337/20th ECS Performance Essentials
Why settle for stock?
ECS Performance Essentials are a special blend of drivetrain, intake, and brake upgrades designed to pick up where the factory left off.
Each is designed to fine tune or enhance the performance and appearance of your VW 337/20th.
For example, the Lightweight Underdrive Pulley Set includes a new alternator, power steering and crank pulley that allows you to use a stock belt - a complete performance refresh.
The ECS Cold Air Intake System allows your engine to make more power by eliminating the restrictive characteristics of the factory system.
