Product Description
We recommend servicing your valve every 3 years, or 20,000 miles, whichever comes sooner
This Blow Off, or Dump valve, is for the BMW N13 1.6 Turbo engines that have the electronically controlled bypass valve. This engine can be found in the F20/F21 and F30 chassis badged as 114i, 116i, 118i, 120i and 316i, 318i and 320i 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, where the original rubber diaphragm splits, which causes a loss of boost pressure. Unfortunately, the failure does not 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.

Our alternative is a fully engineered solution offering significantly improved reliability. Our valve is piston based with no diaphragm to fail, and of all aluminium 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. Not only that the internal spring can be changed for either a stronger or weaker version depending on how much boost pressure you are running.

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.

Expert Answers
Je viens d’acheter la dumpvalve et lors de l’installation j’ai remarqué que les trous n’ont pas été fait à l’usine donc pas moyen que l’air s’échappe Pour ce prix et une marque telle que Forge je trouve ça inadmissible
Hello , this is because the valve purchase was for a recirculating valve. If you require an atmospheric version please follow the returns process on our website for a possible exchange. Thanks
Can i purchase the aluminium connector on its own ?
The boost tap adaptor is available to purchase off the Forge Motorsport website under part number FMBGMCS.
Hello, Is the spring included in the kit is goodly calibrated for an N13 stage 1 ? Thank you
hello , yes the spring is suited for stage 1 vehicles
Hi, I'm planning to buy one of the products. I'm between recirculation and atmospheric. What is the difference between them? I'm looking for one with sound, like supra. Thanks!
The atmospheric valve makes the whooooshing, Psssshhhhttt sound.
The recirculation valve is silent and makes no noise.
It will sound very cool, I cannot say it will sound like a Supra as its completely different.
