Replaces OEM pipe part number 13717604033.
Why upgrade your BMW N55 chargepipe
The stock plastic charge pipe on N55 engines is a well-known weak point. The plastic coupler becomes brittle which leads to cracking, boost leaks and total failure. The Forge Motorsport aluminium hardpipe uses a precision CNC-machined coupler for a durable, permanent solution that stands up to higher boost and spirited driving. It is the essential BMW M2 charge pipe upgrade and a must-have M135i and M235i charge pipe replacement.
