Turbosmart Kompact Dump Valve - Renault Megane 3 RS

The risk of keeping a failing stock valve on Megane 3 RS

  Neglecting to replace the factory diverter valve on a Megane 3 RS is a common mistake that bottlenecks your engine. The stock plastic valve inevitably fails, especially after an ECU remap or an increase in boost pressure. By not upgrading to a Turbosmart Kompact Dump Valve, you lose throttle response (lag), suffer from intermittent power loss, and expose your turbo to unnecessary stress (compressor surge) when lifting off the throttle.

A leaking boost system on your sports vehicle degrades the driving experience and can trigger engine warning lights related to pressure regulation. Don't let a fragile component limit the potential of your premium vehicle.

Why choose the Turbosmart Kompact Dual Port TS-0203-1308?

Machined from aircraft-grade billet aluminum, the Turbosmart Dump Valve is a masterpiece of mechanical precision. Unlike diaphragm-based models, its internal piston is indestructible and ensures a total seal up to extreme boost levels. Its "Shortie" format allows for a Plug and Play installation directly in place of the original unit on the Mitsubishi TD04L turbo of the Megane III RS. Along with the reliability gain, you enjoy a unique sporty sound without upsetting the car's computer, making this purchase a key step in your sports car maintenance.
