I wish some vendor would just make a hinged plastic clamp that fits completley around the OEM charge pipe neck at the throttle body. It would support and strengthen the failure points and would be cheaper and easier to install plus it would be far better at dealing with heat soak and sealing for boost leaks. |

However, when I inquired, I was informed they had no plans to design a replacement pipe and seeing that the N55 was discontinued with the 2018 M2, at this juncture, that's wishful thinking. |

Your basing your statements on elementary physics and looking at the whole system. BMW uses a combination of mechanical, electrical and software for the cars propulsion. until you do the research on how the bmw dme works, air to air systems and the n55, your not going to get it. This will be my last post about the issue. |

Mine broke at the throttle body at 35,000 miles. It's a manual with a JB4 box. Replaced under warranty last week (took out the JB4 box and reverted all the Bimmer code changes before bringing it in). Supposedly it's a new design, but I haven't looked at it closely. I have a BMS aluminum ready to install once the warranty is up in June.

Good luck with all that because it might not fail right away but over many heat cycles, it's susceptible to ballooning and expanding over time.. I know this from experience (radiator silicone pipe).. |

Using silicone hoses for radiators on non-race cars is pointless and actually can cause issues since silicone is permeable to water vapor. |

I'm about to gaff it up, and I bought metal charge pipes in December when I was in the States last because I knew it would happen. Should still be covered by the warranty (expires in June) so will get BMW to replace it as it's due a service anyway, and then put the metal on so it doesn't pop again... |

I seriously doubt they are providing the high quality silicone. I work for a chemical company that specializes in silicon based materials. I can tell you that the really good stuff is very expensive.

I really only hear about problems with the OEM one. Aftermarket metal ones have popped off from a bad install though. Never heard anyone complain that they notice the car is slower after install, so same throttle response is better.

Aftermarket chargepipes are metal. But there's a silicon connector that goes with it.

Physics arguments aside, I suspect nominal performance differences between plastic and aluminium in real world use. The idea of the stock charge pipe cracking and possibly leaving one stranded is reason enough to upgrade. I am strongly considering the purchase of a charge pipe and this thread raises (again?) an interesting question. Does changing a charge pipe put a warranty at risk?. Poochie seems to suggest it does but he runs JB4/Dinan Stage I. I would think that a tune would be far riskier for voiding a warranty compared to changing a charge pipe or IC. Thoughts? |
