Forge Motorsport Atmospheric Blow Off Valve for Renault Megane RS250 RS265 RS275
The Forge Motorsport Atmospheric Blow Off Valve is a high-quality performance upgrade designed specifically for the Renault Megane RS250, RS265, and RS275 models. Made from billet aluminium, this blow off valve improves throttle response and increases clamping load to maintain boost pressure more reliably.
Unlike single piston or diaphragm diverter valves, the Forge Motorsport Blow Off Valve features counterbalanced springs and dual pistons to prevent air leakage into the intake system at idle. This design ensures durability and prevents common failures associated with other types of diverter valves.
The dual piston design of this blow off valve allows for longevity and the ability to be serviced and tuned with replacement springs if required. This kit includes a blanking plate to replace the original or OEM valve, preventing any issues with loss of boost pressure.
The Forge Motorsport Blow Off Valve kit also includes a choice of red, blue, or black silicone hoses. These hoses are constructed with an inner liner of modified silicone known as Fluorosilicone, making them suitable for use with modern long-life coolants, Organic Acid Technology coolants (O.A.T.), or air containing oil mist.
With a lifetime warranty, this Forge Motorsport Blow Off Valve is a reliable and high-performance upgrade for your Renault Megane RS250, RS265, or RS275. Fitting of this part is available at our performance workshop at Progressive Parts.
