A remote Blow off, or Dump Valve Kit for the Ford Focus Mk2 ST225. This uses a twin piston valve to ensure compatibility with the engine management system and a custom silicone hose to ensure easy installation. This valve can be installed in combination with the OEM valve, or on it's own by using one of our blanking plates.

The Forge valve uses an aluminium piston and is totally rebuildable. It’s also configurable for different levels of boost pressure e.g. on a remapped car, by simply changing the piston preload spring inside the valve.

  • The Forge atmospheric Blow Off valve for the Ford  is  made from billet aluminium.
  • This atmospheric blow off valve dumps the charge-air to atmosphere creating the "Whoosh" sound when the throttle is lifted.
  • This improves the throttle response and increases the 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 blow off valves suffering any of the failures associated with single piston and diaphragm type diverter valves.
  • The valve itself is of dual piston design for longevity with the ability to be serviced and tuned with replacement springs if required. (See below)

The hose is available in red, blue, or black, and the valve is available in black. Please select your choice from the options above.

  • The Forge silicone hoses in this kit have been designed to include an expensive inner liner of modified silicone known as Fluorosilicone. This means the hoses are suitable to be used with either modern long-life coolants, Organic Acid Technology coolants (O.A.T.) or air containing oil mist.
  • The construction of the hoses has been engineered to exceed that of the OEM fitments and will enhance any engine bay both technically and aesthetically.
  • The use of a Fluorosilicone liner ensures that Forge silicone hoses are the clear market leader.
  • Lifetime warranty

Really like these for casual summer outfits
Size: 10.5, Color: White
These are really nice kicks. Stylish, comfortable, and eye catchy for sure. Not too heavy, good price, and fit well. These are great, casual white shoes for a summer outfit. I gave it 4 out of 5 stars as these do pick up and hold onto dirt and smudges more than I’d like to see. Yes, I know, white shoes are magnets for this stuff, but these tend to scuff and discolor more than I would have assumed. I live in an area with lots of bad weather most of the year so I only get a chance to wear them for a few months of the year unless I want to brave the wet and muddy weather. If you live in an area that has lots of sun and are willing to put these to the test and clean them often, I would say go for it.
