Turbosmart Dual Port Dump Valve - Renault Clio 4 RS

The risk of keeping a stock valve on your Clio 4 RS

  Ignoring the weakness of the factory diverter valve on a Clio 4 RS is a costly mistake for any enthusiast. The stock valve, made of plastic with a fragile diaphragm, will inevitably leak—especially after an ECU remap. By not upgrading to the Turbosmart Kompact Dual Port, you lose throttle response (turbo lag), suffer from boost pressure drops, and risk premature damage to your turbo bearings due to compressor surge.

A porous boost system on your sports vehicle degrades driving pleasure and can trigger limp mode or warning lights. Don't let a standard component bottleneck the performance of your premium vehicle.

Turbosmart TS-0203-1057: The Benchmark for Renault Sport

The Turbosmart Dump Valve is machined from aircraft-grade billet aluminum, guaranteeing a total seal even under extreme boost levels. Its Dual Port system offers the best of both worlds: an atmospheric discharge for that sporty sound and internal recirculation to maintain a stable airflow for the sensors. This is a key step in your sports car maintenance for anyone looking to secure their intake circuit. Thanks to its "Plug and Play" design, it fits perfectly into the Clio IV RS engine bay without heavy modifications.
