Forge Motorsport Blow Off Valve and Kit for the Ford Focus ST 225 MK2

Product Description

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 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.

Compatible Vehicles

Note that the models listed here have either had the part fitted by us or a customer or they are listed as being compatible on industry parts databases. Where it has not been directly fitted by Forge there will then be a separate May Also Fit tab where the make and model will also appear and which details our no-risk approach to purchasing this product, so it is worth checking there as well.

Warranty Information

The majority of Forge Motorsport products come with a limited lifetime warranty (brakes pads excluded). All warranty claims must be accompanied by the original proof of purchase to enable us to help you. Failure to supply this proof will result in your claim or enquiry being denied.

Do not use aggressive (acidic) car cleaning products, particularly traffic film remover solutions or shampoos to clean your intercooler, radiator, or oil cooler. The use of these products can damage Forge Motorsport cooling systems and invalidate your warranty. These are often found at car washes. A light, warm, soapy solution (free of harsh acidic cleaning compounds) should be used to clean you cooler and thoroughly rinsed away. We recommend that you should inspect your product on a regular basis for bent and/or crushed fins. Any bent fins should be carefully straightened to allow ambient air to pass through the core face. At the time of installing your Forge radiator, an approved coolant must be used and added to the coolant system. Be sure you never mix coolant and always use distilled water.

This warranty does not apply to any defect in the goods arising from fair wear and tear, wilful damage, accident, negligence by you or any third party, use otherwise than as recommended by the supplier, failure to follow the supplier’s instructions, or any alteration or repair carried out without the supplier’s approval.
