High Flow Valve for Audi S3 (8P), VW Golf Mk5 ED30, & VW Golf Mk6 R SKU: FMDV8PS3-BLU

Here’s a breakdown of the High Flow Valve — specifically the Forge Motorsport High Flow Valve (SKU FMDV8PS3-BLU) for turbo cars like the Audi S3 8P, VW Golf Mk5 Edition 30, and VW Golf Mk6 R:

🚗 Part Summary

🔧 What it is:

This is a high flow vacuum-operated twin-piston valve that can be used either as a recirculation valve (diverter valve) or a blow-off valve on turbocharged EA113/EA888 2.0 T engines found in the Audi S3 (8P) and certain VW Golf Mk5/6 models. 

It’s designed to replace the OEM valve with a version that can handle higher airflow volumes — useful when you’ve increased boost pressure or added supporting mods. 

⚙️ How it works:

• The valve uses a vacuum-operated twin piston design that lets boost pressure vent quickly relative to stock units.
• It’s configurable as either a recirc valve (keeps metered air in the intake) or a blow-off valve (vents to atmosphere), depending on how you install it.
• Comes with a full install kit — hoses, vacuum lines, adaptor fittings, clamps, and hardware.  

📦 Included in the kit:

• Forge Motorsport FMDV8PS3 valve body
• Wiring harness & solenoid
• Vacuum tubing and hose clamps
• PCV adaptor kit
• Silicone hoses (your choice of blue, red, or black)
• Brackets, fittings, and mounting hardware
• Installation instructions and Forge sticker  

🛠️ Fitment:

Intended for:

• Audi S3 (8P) with EA113/EA888 turbo engine
• VW Golf Mk5 Edition 30
• VW Golf Mk6 R
  (And often compatible with other 2.0 T models using the same turbo setup — check your engine details before purchase.)  

⏱️ Maintenance:

Forge recommends servicing the valve every ~3 years or ~20,000 mi to keep it operating well.
