The BMW N55 inline-six turbocharged engine is the powertrain that defined a generation of BMW performance — smooth, powerful, and unmistakably BMW. This used BMW N55 engine is a genuine OEM unit sourced from low-mileage donor vehicles and inspected before shipment. Found in the 135i, 235i, 335i, 435i, 535i, 640i, and X-series applications, the N55 produces 300 to 320 horsepower with BMW’s TwinPower Turbo single-scroll technology. If yours has failed, replace it the right way — with the same engine that built the reputation.

The N55 Engine is among our best-selling products, as we provide the best deals and discounts on all our products.

N55 fitment depends on your vehicle’s chassis generation and production date. The N55 engine changed over time, with updates to the crankcase ventilation system and charge air cooling. E-series models (E82, E90, E60) and F-series models (F22, F30, F10, F13) use different oil pans, wiring harnesses, and exhaust manifolds. We use your VIN and our application cross-reference to confirm the exact N55 variant for your vehicle before shipping.
BMW N55 rebuilds at specialist rates carry significant cost, particularly for Valvetronic motor service and charge pipe/intercooler replacement that is often needed alongside the engine work. A used OEM BMW N55 engine gives you a complete, factory-assembled inline-six at a known price that restores the smooth, refined power delivery that makes BMW’s F-series and late E-series cars drive the way they do. The N55 is the engine that defines the driving character of these cars. Restore it correctly.
Every used BMW N55 engine ships with up to a 90-day warranty and arrives within 2 to 5 business days. Installation is not included, but we can help you find a qualified BMW or independent European specialist. These are genuine BMW OEM engines, and we stand behind every unit we ship.
