DCI on 335I do or dont?

jhandy2 · 03-04-2018, 01:03 PM

new into 335s and wasnt sure if it was good for them or bad, read the info about fitting them and all the hot air vs old air arguments, however im more concerned about intake/oil temps and killing MAFS as they used to rocket on a few of my old cars when cones were fitted

prdoper cais would be better,as you have said..heat/oil etc on maf sensor.never seen many proper closed air induction systems on these cars,,when i had my focus st therevwas always problems with cone(group A) filters,,the advice was to just get rid of them.

Intake temps aren't a problem as the air has yet to go through the Turbos so it's only going to get hotter.
