This Blow Off, or Dump valve, has been developed for the Toyota Yaris GR Turbo engine that has the electronically controlled bypass valve OE Part no. It is recommended for any vehicle where the boost pressure has been increased by an ECU software upgrade and for unmodified vehicles operating in warmer climates, as a solution to the many failures that have occurred. Unfortunately, the failure doesn't always result in a check engine light as the valve can still be blown open by the boost pressure, so you may not be aware that you are losing power due to this.
This prevents the diaphragm from sealing. The Forge motorsport valve solution is available in either Atmospheric where a noise is heard when the throttle is lifted or the Factory type non noise recirculating valve. Our alternative is a fully engineered solution offering both significantly improved reliability. The Forge valve is piston based, there is no diaphragm to fail, and of all aluminium billet construction, it replaces the original unit with a pressure/vacuum operated piston valve that still also retains the desirable OEM ECU control, over valve actuation.1 x 2.5m of 4mm Vacuum Tube. 1 x 4mm Brass T-piece. 1 x 3 port Solenoid and fixings. 1 x Uprated Red Spring. 1 x Forge USB Instructions.

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.
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. If this is the case you will be contacted within 24 hours.
