The 2004 BMW X5 4.4i is equipped with BMW’s N62 4.4-liter naturally aspirated V8 engine, producing 320 horsepower and 330 lb-ft of torque. This aluminum-block engine features BMW’s Double-VANOS variable valve timing system and an electronic throttle. The N62 was BMW’s first V8 to use Valvetronic technology for throttle-free load control. It’s paired with a 6-speed automatic transmission and BMW’s xDrive all-wheel drive system as standard equipment. The engine provides strong acceleration with 0-60 mph times around 6.5 seconds while maintaining reasonable fuel economy for its size and power output.

The 2004 BMW X5 belongs to the E53 generation (2000-2006), and most mechanical parts interchange across these model years. Engine components from the 4.4L V8 are compatible with 2003-2006 X5 4.4i models, though early 2000-2002 models used a slightly different M62 engine. Body panels, interior trim, and suspension components generally fit 2000-2006 models, with minor variations for mid-cycle updates. The 6-speed automatic transmission is compatible across 2004-2006 4.4i models. Always verify part numbers when sourcing components, as BMW made running changes throughout production that can affect compatibility even within the same model year.

The N62 4.4L V8 in the 2004 X5 has moderate reliability with some known issues to monitor. The engine itself is generally robust when properly maintained, but the VANOS system can develop problems and valve cover gaskets commonly leak after 100,000 miles. Regular oil changes with BMW-approved synthetic oil are critical, as the engine is sensitive to oil quality and change intervals. The cooling system requires attention, particularly the expansion tank and water pump. With proper maintenance including addressing known weak points proactively, these engines can provide reliable service well beyond 150,000 miles. However, deferred maintenance can lead to expensive repairs.
