We recommend servicing your valve every 3 years, or 20,000 miles, whichever comes sooner
Suitable for the BMW 335 fitted with the N54 Twin Turbo engine. This alloy hard pipe fits to the throttle body and incorporates our high flow blow off valve. This valve, fresh from our R&D department, is the largest displacement valve that Forge have ever made! Featuring a 50mm (2”) aluminium piston so that there are no issues with split diaphragms, we have not found the power handling limits of this valve yet!
The piston uses heat stabilised viton o-rings and high temperature grease to ensure a long life with minimal wear and very long service intervals.

Perfect fit and great sound! Nice and snug sealing on the throttle body! no leaking here!
awesome product. great sound from their new blow off valve. my only complaint is the the silicone pipe is difficult to get on in the right position. it has blown off the intercooler pipe 3 times since install. however the quality of the pipe and kit itself is top notch. install instructions come on a thumb drive. which is nice. but not effective considering i dont have a computer near where i work on my car. i prefer paper instructions. all in all it is a great pipe and very pleased. i just have to find a way to get this hose clamp to stop popping off.

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.
