Product Description
The plastic charge pipe is one of the N55's (F2x, F3x, F87) known weak points. Heat cycling makes the factory coupler brittle, and over time it cracks, fractures and eventually fails — usually taking your boost with it. We've had a steady run of enquiries from owners after exactly this failure. Our alloy replacement fixes it for good: a CNC coupler that won't go brittle like the original.
Fitment
Will not fit xDrive. On xDrive cars the steering rack sits where the pipe needs to go, so there's no clearance.



What you get
- CNC-machined alloy coupler and flanges — no more brittle plastic, no more cracking
- Sharper throttle response and reduced turbo lag
- Retains the factory-style O-ring throttle lock flange for a clean, OEM-style fit
- Precision CNC couplers for quick, easy connection and disconnection
- Powder-coated hard pipes for a durable, hard-wearing finish
- Keeps your factory electronic diverter valve
- Water/meth injection boss built in — run it if you want it, or fit the supplied plug if you don't
- Direct replacement for OEM part 13717604033
Before you fit
Keep your original O-rings and seals during removal — they're reused on the Forge hoses.

Warranty
All Forge Motorsport products come with a limited lifetime warranty. 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 contact our customer service team.
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.
