Description
Product Description
Similar to many of the newer VAG engines, the latest 1.0 TSI power plant is not equipped with a diverter valve fitted as standard, Forge Motorsport has developed a twin piston dump valve that not only gives you a loud audible sound when lifting off the throttle, but also increases the throttle response during gear changes by reducing turbo lag. It has been designed to help the turbocharger maintain its rotational speed ready for when you accelerate, whilst also taking the strain away from the impeller. Without removing this stress from your turbo, it can lead to premature failure especially on remapped engines and modified vehicles.

This valve kit allows the fitment of our fast response blow off valve preventing turbo surge and prolonging the life of your engine’s turbocharger. The kit includes all the necessary hardware and step by step installation instructions for any car enthusiast with appropriate garage tools to fit at home, in just a couple of hours!



Due to the exposed position of the OEM boost pipe and the nature of heat cycle, the plastic that the OEM pipe is made from can deteriorate over time, becoming brittle and susceptible to boost leaks. This kit totally replaces this plastic pipe from turbo to manifold with a multi-ply silicone hose (available in a choice of red or black).


Highlights:
- CNC machined billet couplers and components
- CNC machined twin piston Forge valve.
- Two hose options: red or black (Custom colours available but will incur a 50% non-refundable deposit and a lead time of 8-10 weeks)
- Forge Motorsports dump valve will not bring on any check engine lights (EML)
- The hose has a quality inner lining of modified silicone known as 'Fluorosilicone'. This means that the hose will stay bright and vibrant and will not deteriorate over time. Forge Motorsport lined hoses are suitable to be used with modern long-life coolants, Organic Acid Technology coolants (O.A.T.) and oil mist. The construction of the hose has been engineered to exceed that of the OEM fitments, the Forge Motorsport hose will enhance any engine bay both technically and aesthetically.
- We cannot guarantee that this product will fit with all aftermarket intakes.
- Lifetime warranty
- We recommend servicing your valve every 3 years, or 20,000 miles, whichever comes sooner

This part will take approximately 1 hour to fit.

Warranty
10 Year Warranty Information
The majority of Forge Motorsport products come with a limited 10 Year 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.
For further information, please call our customer service team on +49(0)3222/1097-308 or email info@forgemotorsport.eu.
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.
