Description

Forge Motorsport - Twin Piston Blow Off Valve with Side Vacuum Nipple (Alloy finish)This version of our popular FMDV004 valve has the vacuum connection on the side of the valve which is ideal for those applications where space is restricted. Made from billet aluminum, this atmospheric diverter valve dumps the charge air to atmosphere creating the "Whoosh" sound when the throttle is lifted. This increases both quicker throttle response and higher clamping load to maintain boost pressure more reliably. Unlike single piston or diaphragm

This version of our popular FMDV004 valve has the vacuum connection on the side of the valve which is ideal for those applications where space is restricted.    

Made from billet aluminum, this atmospheric diverter valve dumps the charge-air to atmosphere creating the "Whoosh" sound when the throttle is lifted. This increases both quicker throttle response and higher clamping load to maintain boost pressure more reliably. Unlike single piston or diaphragm diverter valves, this uses counter balanced springs and dual pistons to prevent the valve from leaking air into the intake system at idle. This prevents our diverter valves suffering any of the failures associated with single piston and diaphragm type diverter valves.

Fitment Guide: Suitable for most turbo cars with an Air Flow Meter. Dual-Piston Atmospheric Valves and Valve Fitting Kits

All Forge Motorsport Dual-Piston Atmospheric Valves have been designed and built with the intent of venting 100% of the residual charge air remaining in your forced induction system to the atmosphere at throttle lift. While we have incorporated many elements into the design of the Dual-Piston valves to aid in their compatibility with mass air-flow sensor equipped vehicles, we cannot always guarantee that each individual’s application will be compatible with a valve that vents the charge air into the atmosphere.

Forge Motorsport nor any of it’s Authorized Distributors can assume any responsibility for any adverse effects resulting from the installation of this valve onto a vehicle whose engine-management-system, whether factory or aftermarket, is not capable of compensating for the loss of metered air through a vent-to-atmosphere valve such as this.

 Please contact us if you are unsure whether this product is suitable for your vehicle.

In The Box:
1 x FMDV004A Valve
1 x Forge Sticker

The valve has a port size of 25mm

Cute and good product!
Only thing wrong was the bottom of the top tray had a gap between the side and the bottom and a small cosmetic damaged spot where the screw went through too far. Other than that, it is good for my purpose of a coffee cart for a dorm room. It’s really cute and bigger than I thought it would be.
