So I am now almost finished installing the M5 intakes along with the Ramair dry filters. everything is bolt on except obviously I've removed the airbox filter from the original M5 parts.My plan is to fabricate a channel to direct the air around the radiator (similar to the M5) and onwards to a heat shield to avoid heat soak.
The map sensors are also plug and play between applications, I've fitted new gasket seals and bolts just about everywhere for best practise. I can confirm that X6M PCV lines reach the the M5 intakes on the turbos perfectly except the short one on the left side of the manifold cover. A little fabrication of a smaller vacuum line is required... (nothing major) see pictures below
The biggest PITA at the minute is that I am trying to re-route all lines and wiring harnesses as much as possible to get a cleaner look ...
