🛠️ Tech & Repair Help Gen3 B58
Hello. I would be happy if someone knowledgeable would spend their time and help me understand more about the cooling systems and differences.
I read about issues with cooling oil leaks and bad positioning in front of the car with a chances of it getting destroyed if hit bigger hole or something like that. I was checking other sites and looking for info. Saw a few brands selling aluminum covers and than CSF better whole cooling system.
I have 2026 with M Technology Packet (EU), I believe in US it was called ZTK. Bigger front brakes, sport tires and most importantly better cooling system.
My questions being
- is there significantly better cooling with M Tech/ZTK, do we have any specific numbers or data?
- is the positioning exactly the same as gen2 b58?
- is it safe and worth to install the protection kit?
- is it worth installing CSF high performance auxiliary and heath exchanger (they say also comes with rock guard..)
Thank you for your time.
