Product Description

We recommend servicing your valve every 3 years, or 20,000 miles, whichever comes sooner

Yet another first for the Volkswagen and Audi Tuning Market from Forge Motorsport!

With the introduction of the VAG TSi Turbo Engine, we developed a patented atmospheric blow-off adapter specifically designed to fit this application. Simple in execution, yet offering the desirable atmospheric blow-off valve sound, this product has been designed to be fully compatible with the Bosch engine management systems employed.

This is not only a high quality replacement for vehicles fitted with the OEM solenoid valve part number 06F 145 710 D, but will fit earlier applications of the 2.0 FSiT, the later TFSi 2 litre, and the 5 cylinder TTRS.. 


In The Box:
1 x FMDV14T Blow Off Adaptor
3 x M6 x 40 Socket Cap Bolts
1 x Forge Sticker

Item purchased more than exceeded expectations while also opening up an issue I didn't know existed with mycar when removing the diverter valve to fit the spacer. I discovered a split seal causing a boost leak. New dv ordered and fitted with spacer feels like a brand new car and sounds absolutely incredible twinned with my ramair induction kit

Ordered this for my audi ttfsi. Product of good quality and good delivery communication.
No instructions in the box saying what direction the blow off exhaust holes needed to be but fitted with words for getting facing ground and seems to be OK.

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.
