Moin, so I would like to know if anyone has already had experiences with the BSR Optiflow Intake?! I have already looked at the system of K&N, but I am completely averse to it, because the control unit does not get any “fresh air” in any way and could therefore possibly overheat it. I like the system of BSR already more, because the air filter is still shielded by a complete box which is roughly identical to the original part, also the connection for the fresh air supply is guaranteed. I would like to install something like this, however, because the control unit is usually cooled by the flowing air. If anyone has had personal experiences with it, I would be happy to hear if a cooling of the ECU is actually guaranteed. Point 2 Besides, I wanted to build additional instruments, mainly oil temp and oil pressure, but charging pressure would also be nice to thank you. These new cars have something that is no longer in it, actually something that is really useful!
