If you own a BMW G20 M340i, an A90 Toyota GR Supra, or any B58 Gen2-powered car, the factory plastic charge pipe is one of the first weak points worth addressing. We have been running the FTP B58 charge pipe on our builds and here is an honest look at what it does, how it installs, and why it matters for your BMW turbo system.
The Stock B58 Charge Pipe Problem
BMW's OEM charge pipe is plastic. Under stock boost it holds up fine, but the moment you push harder with an ECU tune or sustained spirited driving, that plastic pipe becomes a liability. Cracks, boost leaks, and outright failures are well-documented across B58 forums and communities.
The FTP BMW B58 charge pipe replaces that brittle factory plastic with aluminum construction that handles aggressive boost pressure without flexing or cracking. It is a direct OEM replacement for part number 13718651066, so fitment is bolt-on with zero modifications required.
What the FTP B58 Charge Pipe Delivers
Key Features
- Increased Flow: Larger internal diameter and optimized geometry reduce turbulence and support higher boost pressures
- Direct OEM Replacement: Bolt-on fit for OEM part 13718651066, no drilling or custom brackets
- Caliber Increase: Larger piping size maximizes airflow into the engine
- 3-Ply Silicone Couplers: Premium reinforced couplers replace weak factory rubber connections
- Bung for Water Injection: Built-in provision for water injection systems, ready for advanced tuning
- Aluminum Construction: Replaces the factory plastic pipe that cracks under boost pressure
Real-World Driving Impressions
After installing the FTP charge pipe, the difference is most noticeable in turbo spool response. The engine feels more immediate off-boost, and mid-range acceleration between 3,500 and 6,000 RPM is noticeably snappier. For daily driving, it translates to a more responsive throttle feel. For tuned cars, it removes a common bottleneck that limits what your ECU map can safely deliver.
This is not a part that adds massive horsepower on its own. It is a foundation upgrade. When paired with an intake, intercooler, or ECU tune, the charge pipe ensures your B58 turbo system works together efficiently without a weak link in the boost path.

Installation Tips from the Community
Installation is straightforward. If you have done basic underhood work on your BMW before, this is a comfortable DIY job in about 1-2 hours. All hardware and silicone couplers are included in the box. For shop installs, most BMW-familiar technicians knock this out quickly.
A couple of tips from owners who have done it: take your time with the coupler clamps and make sure everything is seated properly before tightening down. Double-check all connections for boost leaks before driving aggressively. Simple process, solid results.
Building Your B58 Platform
The charge pipe is one of the smartest first upgrades for any B58-powered car. Many FTP owners pair it with intake pipes, intercooler upgrades, and ECU tuning to build a comprehensive and reliable performance package. Start with the foundation, then build from there.
