Searching for used BMW engines for sale? Moon Auto Parts stocks one of the largest inventories of used BMW engines in the United States. Every used engine in our catalog is sourced from low-mileage verified donors, compression-tested by certified technicians, and VIN-verified for exact fitment. The pre-owned BMW engine consistently has a market in the U.S. and beyond.
The BMW B58 engine, BMW V8, BMW V10 engine, BMW M50, BMW i8, BMW N55, and BMW inline-6 are among the most popular engine families in the United States. In addition, BMW's illustrious motorsport legacy includes touring cars, sports cars, and the Isle of Man TT. Furthermore, based in Germany, they manufacture vehicles in the United States, the United Kingdom, South Africa, Brazil, China, India, Mexico, the Netherlands, and Germany. Moreover, they developed a variety of series, comprising the BMW, BMW i, BMW M, BMW X, and BMW Z. Notably, at the Spartanburg facility, they manufacture U.S.-exclusive models like the X3, X4, X5, X6, X7, and XM sport utility vehicle models.
The BMW engine lineup spans four major families that account for the overwhelming majority of replacement demand. Understanding which family your vehicle uses is the first step before sourcing any replacement.
The N52 straight-six powered the 325i, 328i, 525i, 528i, X3, and Z4 across the 2006 to 2013 model years. Producing 215 to 230 hp depending on the variant. It is one of BMW's most respected naturally aspirated units, smooth, responsive, and genuinely long-lived when oil changes are maintained. A used BMW 3 Series engine or used BMW X3 engine from the N52 family represents outstanding value from a well-documented, highly reliable donor pool.
The N55 replaced the twin-turbo N54 in 2011 and became BMW's dominant six-cylinder platform through 2016, powering the 335i, 435i, 535i, 640i, X4 xDrive35i, and X5 xDrive35i. Producing 300 to 306 hp, the N55 delivers strong real-world performance with better oil system reliability than the N54 it replaced. A BMW N55 engine for sale from Moon Auto Parts covers all major applications from 2011 through 2016 with documented low mileage.
The B58 is BMW's current-generation 3.0L turbocharged six-cylinder, powering the M340i, 440i, 540i, 740i, X3 xDrive30i, X5 xDrive40i, and X7. Producing 335 hp in standard tune and up to 382 hp in M Performance applications, the BMW B58 engine represents a significant reliability improvement over earlier turbocharged inline-six units. B58 replacement demand is growing rapidly as 2016 to 2020 examples accumulate mileage.
The N62 naturally aspirated V8 powers the 545i, 550i, 645Ci, 650i, 745i, and 750i across the 2002 to 2010 era. The N63 twin-turbo V8 took over from 2010 onwards in the 550i, 650i, X5 M50i, and M550i. For high-performance applications, the BMW M3 engine has evolved through multiple generations from the S65 V8 to the current S58 engine powering the G80 M3 and G82 M4 Competition, both of which are available in our inventory for qualified replacement orders.
BMW engine replacement requires a higher level of specification precision than most mainstream brands. BMW uses multiple Valvetronic configurations, VANOS timing variants, and emissions specifications (California CARB vs federal) within the same model and year. The N52, for example, comes in N52B25, N52B30, and N52KP variants with different power outputs and electronic configurations that are physically similar but electronically incompatible. Every low-mileage BMW engine we stock comes with documented mileage from donor vehicle records, not estimates.
