Engine radiator MISHIMOTO or OEM BMW

Replaced it with mishimoto and haven't looked back. Holds much more coolant that OEM and does a much better job cooling.

OEM radiator. Replaced radiator on visit 5 (today). Bmw closed loop network is what eventually led to the radiator being checked as they’ve seen aftermarket radiators actually cool the cars too much, therefore sending the tstat fault in cold weather (this issue occurred first last winter for me, then again 5 times this winter.. all same fault code). Confidence that this is the root cause fix seems to be high so fingers crossed I won’t be updating this in a few days.

Replaced OEM with a mishi, Fitment is good part reason I went with it was I replaced the fans with mishimoto fans and it all slid in nicely

I have a mishimoto radiator. At idle the highest I get to is 196 F then it drops down to about 185 F. While driving I’m usually averaging about 178 - 190 F if I’m not in stop and go traffic.

Mine bolted right in, no issues, and works spectacularly.

I have a 2008 e90 335xi FBO with 197k miles and I am still on my original BMW radiator. If the stock original BMW stamped one works well... why experiment?

N54 335i - 200k miles radiator upgraded

Recently got rid of the mishimoto radiator and went back to the updated larger radiator

BMW N51 engine, SULEV radiator, these cars came with a sensor that sticks to the side of the radiator for emissions compliance. Can't even get it aftermarket anymore (last time I checked) new radiator without the sensor is like $150, with the sensor is close to $800, and no you cannot use the old sensor, if you try sticking the old sensor to a new radiator it won't recognize it and it will trigger the check engine light.

stay away from mishimoto, their radiator quality is sub par
