Whether it is an early E28 or E34, an evolved E60, or a new F10, the BMW 535i has always been an up-market offering within the 5-series line for buyers who want to get exceptional performance and power out of a more fuel-efficient engine. The 535i has always come equipped with a straight 6-cylinder engine, and produced more horsepower than a 525i, 528i, or 530i. Additionally, a BMW 535i still benefits from the same performance-oriented engineering and construction methods used across all of their vehicles, and includes all the luxury options and amenities one would expect from BMW. BMW 535i parts are among the finest in the executive car market, and never disappoint. Fun fact: the BMW 535i has never actually had a 3.5L engine. Early models included a 3.4L and later models a 3.0L.
