BMW B58 Engine Guide: Everything You Need To Know

►BMW's B58 engine has quickly become one to beat. It's been a staple across BMW's entire lineup since it first arrived in 2016, appearing in every sedan and coupe in one trim or another from the 3-series through the 8-series, and every SUV from the X3 through the X7. It even appears in the latest Toyota Supra sports car and the Ineos Grenadier 4×4. The versatility it provides from its reliability and eagerness to make power lends it to all of those vehicles in the best way. But that's only if they're cared for properly.

Rather than taking your BMW to an independent shop or a dealership to get hit with an expensive repair bill, you can follow along here and learn all about what your B58 straight-six may need in the future. Alex Nelson, FCP Euro's Automotive Design Engineer and BMW Expert, has learned all there is about this engine family, built out FCP Euro's catalog to support it, and is now here to bring you up to speed on the B58. Whether it's just another engine in your commuter or the genesis of a high-powered build, here's everything you need to know.
