- Which BMW models and engines does this set fit?
- It is listed for the N62 4.4L V8 in the 2002-2006 545i, 645Ci, 745i and X5 (E53, E60, E63, E66). Confirm your engine code and part number before ordering.
- Does it fit both the 4.4L and 4.8L N62?
- The listing covers the 4.4L N62 only. The 4.8L N62B48 in the 550i, 650i, 750i and X5 4.8is uses different pistons and rings, so do not assume it fits.
- Do the part numbers match my car?
- The set is listed against 11257519916 and 11257515760. Check these against your VIN or engine number with a BMW parts reference before you buy.
- Can I install these myself?
- Only with engine-out experience and measuring tools. Pistons and rings need correct bore clearance, ring end gap and honing, so most owners use a machine shop.
- Is this a performance upgrade?
- No. It is a stock replacement set for worn N62 internals. It restores compression and oil control rather than increasing power.
- What is in the set?
- The listing describes one set of pistons and rings. It does not state gaskets, bearings, pins or other rebuild parts, so plan to source those separately.
