This is true above but I would make sure you also get a model with a Oil Cooler, this makes a huge difference. My prior e90 did not have one and it will run really hot all the time around 270-290... This LCI does not go past 230 even on 90+ degree weather... I'm not exactly what year they started (think march 08 production for the e90) but its good for the long run
