F30 335i Track Package / P337A Cooling Retrofit – Which RealOEM diagrams and parts are needed?
Hi guys,
I’m trying to understand the full retrofit for the F30 335i Track Handling / Track Package cooling setup, option P337A.
My car is a 2014 F30 335i, and I’m looking at the RealOEM cooling diagrams here:

The part that confuses me is that there are several different cooling diagrams, and I’m not sure which one shows the complete correct setup for the P337A retrofit. I’m mainly trying to figure out all the parts needed for the extra cooling system, including the driver-side auxiliary radiator, the front auxiliary/transmission cooler area, brackets, air ducts, hoses, pipes, and any smaller mounting parts.
The attached picture shows the areas I’m talking about.
Has anyone retrofitted the full Track Package / P337A cooling system on an F30 335i?
Which RealOEM diagrams should I use, and do you have a complete parts list or checklist for everything needed?
I’d really appreciate any advice from someone who has done this retrofit or compared the standard cooling setup vs the Track Package setup. Right now the diagrams are a bit confusing and I don’t want to miss brackets, ducts, hoses, or small parts.
Thanks!
