Product Description

The Go Fast Bits T9388 DV+ Diverter Valve is a performance-oriented replacement for weak or restrictive factory diverter valves on many modern Mercedes-Benz turbo engines. Designed with GFB's DV+ pilot-actuated technology and an integrated low-profile solenoid, this valve progressively opens in response to boost pressure, improving throttle response and maintaining boost more effectively than many original plastic-bodied diverter valves. The precise metal piston and integrated solenoid design also helps eliminate common boost leaks seen on late-model European turbo engines.

This direct-fit diverter valve installs easily in place of the stock unit using the provided adapter wiring loom and mounting hardware - no custom wiring or modifications are required. The DV+ design ensures smoother power delivery under throttle modulation compared with binary OEM valves, delivering a more responsive feel and faster boost recovery during spirited driving. Built for performance and durability, the T9388 is backed by Go Fast Bits' lifetime replacement program for peace of mind.

Fitment for the Go Fast Bits T9388 is confirmed for a broad range of Mercedes-Benz turbocharged vehicles from roughly 2011 through 2021, including C-Class, A-Class, CLA, GLA, E-Class, GLC, AMG GT, and AMG-branded performance models such as the CLA45 AMG and C63 S AMG. This makes it an excellent upgrade for enthusiasts seeking improved boost response and durability on late-model Mercedes turbo applications.
