Late build cars may need to replace the throttle body boots with the slim style found on early cars.



Late style boots



If yours has 'large' inlet boots you may need 6x of the following:

To add, both the CSL Air Shut Off Valve and the CSL Crankcase Hose can be adapted from the stock ones with appropriately fitting vacuum hoses. I did this for the air shut off valve and that requires 8mm ID tubing. Can't comment on the size required for the crankcase hose, as I bought that part new.

Also, the boot clamps on the throttle body side are reusable, but the ones on the airbox side are technically not. I say technically because you could pry them off and recrimp them once on the CSL box, but you could easily mess them up in the process.

EDIT: Here's a PDF of the spreadsheet I made for my install (forum won't let me upload .xlsx files). This is on a 6MT 02 M3 with an MSS54 non-HP DME that I converted to HP spec. I decided to not run a flap, so I didn't purchase that, nor did I purchase the electronics required to convert the DME to full CSL spec.

By any chance does anyone know what is the part number for the MAP sensor DME X6003 Terminal socket pin or socket pin size?, which is needed to be added for the signal in dme. Can't seem to find this info anywhere.
