The BMW engine air filter part number 13717505007 (interchangeable with Mahle LX 778 or factory supercession number 13710151548) is designed for the flagship E65/E66 generation 7 Series. Depending on the engine type, cars using this part number require either one or two physical filter elements per vehicle. The exact US years, models, and unique engine configurations it fits include:
BMW 7 Series (V8 Models — 1 Filter Required)
For the 4.4L V8 powertrain configurations, this part number serves as the single primary engine air filter.
- 2002–2005 BMW 745i (4.4L V8 N62 engine)
- 2002–2005 BMW 745Li (4.4L V8 N62 engine)
BMW 7 Series (V12 & Late V8 Models — 2 Filters Required)
For massive V12 engine builds and early 4.8L V8 updates, the intake plumbing relies on a split dual-airbox system. If you own one of these models, you must purchase a matched pair of two filters to complete a full air intake service.
- 2003–2005 BMW 760Li (6.0L V12 N73 engine)
- 2005 BMW 760i (6.0L V12 N73 engine)
- 2006 BMW 750i (4.8L V8 N62TU engine — Strictly for early production dates through 11/2005)
- 2006 BMW 750Li (4.8L V8 N62TU engine — Strictly for early production dates through 11/2005)
- 2006–2007 BMW 760i / 760Li (6.0L V12 — Strictly for early production dates through mid-2006)
The Hard Production Cutoff Dates
- The Mid-Generation Shift: During the 2006 model year facelift, BMW reworked the engine airbox configurations for the updated N62TU V8 and N73 V12 platforms.
- The Cutoff Windows: The absolute manufacturing cutoff for this filter element format is November 2005 for the 750i/Li models, and August 2006 for the late-run 760Li models. If your 2006 or 2007 vehicle was manufactured after those split-month milestones, it migrates to a newer part number layout.
