Atmospheric dump valve kit for Megane II R.S. and Megane III R.S.

The R.S. Performance closed-circuit dump valve makes it possible to maintain a close-to-original appearance in your engine bay while optimising the performance of your Megane II R.S.
Unlike the open-circuit dump valve, the closed-circuit dump valve retains the original operation by releasing excess boost pressure into the engine intake.
The R.S. Performance dump valve maximises boost pressure while smoothing it across the rev range, boosting your engine's performance.

Benefits :
- Improved turbo response time.
- Does not trigger the engine light.
- Lightweight (robust aluminium piston) and durable (high-temperature Viton seal).
- Easy maintenance (can be completely dismantled).
