Intake air temp

raldenlee · 05-09-2018, 08:19 PM

I have a 2016 228i Msport with jb4 and catted downpipe (map2), and now that summer is almost here I have been wondering if I need a FMIC upgrade. I took it out today and drove around at low 80's ambient temp, logging on jb4 app. Intake temps rose from 82 to high 90's and then after 20 min rest, rose again into 120's in city traffic. Hard to be sure if power loss given city traffic, but is this hot enough to reduce power?

Wait until you realize how hot your coolant is getting. Hotter than most normal cars by quite a bit.
