Buying Engine Parts for a 2021 BMW 440I

On this vehicle, the engine covers the internals and hard parts that build compression and keep oil where it belongs — gaskets, bearings, camshafts, lifters, seals and timing components.

  • Confirm you have the 3.0L L6 Turbocharged engine — every part on this page is matched to it.
  • Read the notes on each row for position, trim and spec qualifiers before you order.
  • Where labor overlaps, replace the seals and gaskets for anything you open up; a timing job should always include the tensioner and guides, not just the belt or chain.
  • Cross-reference the manufacturer part number against your old part or a service-manual listing.

What do the market flags (US, CA, MX) on each part mean?

They show the market for which the manufacturer published application data for that part — where the vehicle was first sold, not where the part was made. If your 2021 BMW 440I was originally sold in the US, the safest choice is a part marked for the US market.

How do I make sure a part fits my 2021 BMW 440I?

Every part on this page is matched to the 3.0L L6 Turbocharged engine.
