Moving from a saloon to the X5M F95 or X6M F96 changes the intake layout completely. This piece covers carbon intake fitment, S63 downpipes, cooling in a taller nose and the M60i and XM variants.
The X3M F97 and X4M F98 use the S58 engine in a very different engine bay. Here is what changes for a dry carbon intake, what to check on titanium downpipes and how to confirm clearance before ordering.
The F90 M5 and M8 family share a front end that is short on space. This article explains the two-branch intake layout, charge cooling, the S63 exhaust side and the fitment details that decide the job.
Silicone, titanium and stainless steel each solve a different problem on the F80, F82 and F83. This piece separates the three by function, from the front-mount intake to the charge pipes and the exhaust behind them.
The G80 M3 and G82 M4 need intake and charge pipe work planned as one system. This article covers the front-mount layout, the plastic charge pipe, the material choices and what to confirm before ordering.
Hangers carry weight and locate the pipe at the same time. Covers spacing along the run, attachment around the tube, materials and movement, common errors and checks after work.
Titanium and stainless resist corrosion differently, and cleaning follows from that. Covers safe washing, what to avoid, heat colour, protecting finishes and looking after joints and mounts.
Confidentiality in custom work is mostly handling and agreement. Covers who owns a design, how files and samples are held, where the process leaks and what an agreement should cover.
