Go Fast Bits BMW N55 Upgraded Diverter Valve (M135i, M235i, 335i & more)

Upgrade your BMW’s turbo performance and reliability with the Go Fast Bits DV+ Upgraded Diverter Valve – the ideal solution for N55-powered models like the M135i, M235i, 335i, and more. Unlike typical aftermarket blow-off valves that compromise factory tuning, the DV+ offers a smarter approach by enhancing the OEM electronic diverter valve system with stronger, more durable components.

This kit replaces the factory plastic valve internals with precision CNC-machined parts, improving boost response, preventing pressure loss, and ensuring long-term reliability—even under higher boost levels. It retains your car’s factory ECU control and electronics while solving common issues like boost leaks and diaphragm failure. Perfect for tuned or stock engines alike.

Key Features:

• Direct-fit upgraded diverter valve for BMW N55 engines
• Stronger, more durable construction using CNC-machined components
• Improves boost response and eliminates common OEM valve failures
• Retains factory ECU control for smooth, reliable operation
• Ideal for stock or tuned vehicles
• Easy installation—no custom tuning required
