BMW N43

The BMW N43 is a naturally aspirated four-cylinder petrol engine which was sold from 2006-2013. It replaced both the BMW N46 and BMW N45 engines. However the N43 was not sold in countries with high sulfur fuel, therefore the N45/N46 engines remained in production alongside the N43. Compared with its N46 predecessor, the N43 features direct injection.
