Why Buy a 2019 BMW Engine from Auto Power Source

2019 is the widest engineering spread BMW has ever offered in one model year, and it is the year the engine code matters most. A 3.0L six can be a standard B58, a high-output M Performance B58, the M-division S55, or — on the F16 X6 xDrive35i alone — the older N55 that the rest of the range had already left behind. A 4.4L V8 can be a 445 hp N63B44T2, a 456 hp T3, a 523 hp M850i tune, or the X6 M's S63. Displacement alone will not get you a running car; the code will.

All 62 of these engines were pulled from low-mileage donor vehicles, catalogued by VIN and chassis code (F22, F30, F32, G20, G30, G11, G05, G07, F15, F16, I01), and held in our climate-controlled warehouse. Each went through the six-step inspection: VIN-matching against your chassis, compression and leak-down testing by ASE-certified technicians, noise and smoke verification on the stand, visual inspection of VANOS solenoids and oil-feed plumbing, multi-angle photography sent for your approval, and palletized shipping.

You pay a fraction of dealer-new pricing for the same BMW engineering, ship free on a heavy-duty pallet anywhere in the continental U.S., and have 30 days from delivery to return for any reason with no restocking fee. The warranty printed on the listing covers you after install, with extended coverage up to 3 years available. Our fitment-related return rate sits at 0% because we confirm the match before anything ships.

Your 2019 BMW Engine Options: Compared

Most 2019 BMW owners face four real choices when the engine fails:

← Swipe sideways to see all columns →
Option Cost Reliability Warranty Fitment Match
Used OEM (this collection) $$$ Best Value High — tested Included VIN-matched
New OEM (dealer) $$$$$ 2-4× more High Manufacturer Exact
Aftermarket / Reman $$$$ Varies 6-12 mo May adapt
Junkyard $ Cheapest Unknown None DIY

Tested used OEM hits the sweet spot — same engineering as new, fraction of the cost.

2019 BMW Engine Buying Guide

5 things to verify before buying a used 2019 BMW engine:

  1. Match the engine code, not the displacement. In 2019 a 3.0L BMW six is a standard B58, an M Performance B58, an S55 or — on the X6 xDrive35i — an N55. A 4.4L V8 is an N63 at one of three outputs or an S63. The code decides turbo, pistons, charge cooling and ECU map, and the families do not interchange in either direction.
  2. Treat M Performance as its own engine. The M240i, X3 M40i and X4 M40i B58 carries a different turbocharger, pistons, charge cooling and oil supply from the 440i, 540i, 740i and xDrive40i B58. Fitting one in place of the other is not a tune difference — it is a different long block with different ancillaries.
  3. Read the drivetrain label against the nameplate. Four rows in this year's stock carry an xDrive nameplate alongside an RWD drivetrain label, or the reverse — the 230i xDrive, 530i xDrive, 540i xDrive and M240i xDrive listings. Oil pan and front sump geometry differ between RWD and xDrive, so we confirm the drivetrain from the build record rather than the listing text before anything ships.
  4. Check the architecture before the fitment. The i3 and i3s eDrive units, the i8 hybrid drive unit and the W20K06 range-extender twin are four different pieces of hardware, and none of them substitutes for another or for a combustion engine. Ordering across them is an architecture mismatch, not a fitment adjustment.
  5. Confirm the match with your own VIN before you order. Your VIN settles the engine code, drivetrain and build split in one step. Text it to +1-307-441-5554 and we will confirm in writing exactly which unit fits your vehicle before you pay.

Our ASE-certified technicians verify every one of these points against your VIN before any unit ships.

Frequently Asked Questions

Which engine families do you stock for 2019 BMW?
Fourteen: B46/B48 2.0L Turbo-4, B58 3.0L standard, B58 3.0L high output (M Performance), N63 4.4L V8 as three separate rows at 445, 456 and 523 hp, S55 3.0L M twin-turbo, S63 4.4L M twin-turbo, N74 6.6L V12, N55 3.0L single-turbo, the 2.0L plug-in hybrid four, the i3/i3s eDrive unit, the i8 hybrid drive unit, and the W20K06 range-extender twin. The families table above gives the live count for each.
What does ASE-tested mean?
ASE-certified technicians compression-test every cylinder and run leak-down evaluation, plus noise and smoke verification, visual inspection, and multi-angle photography before shipment.
Is the M240i engine the same as the 440i or X5 xDrive40i engine?
No. All three are B58 3.0L sixes, but the M240i, X3 M40i and X4 M40i run the high-output build with a different turbocharger, pistons, charge cooling and map. They do not swap with a 440i, 540i, 740i or xDrive40i in either direction.
Why do you list the 4.4L V8 at three different outputs?
Because 2019 used three N63 tunes: 445 hp on the 650i and X6 xDrive50i, 456 hp on the M550i, 750i, 750Li and X7 xDrive50i, and 523 hp on the M850i. They share the hot-vee architecture but not the turbos, cooling or calibration. The X6 M's S63 is a separate M-division engine again.
Why does the X6 still use an N55 in 2019?
The F16 X6 ran to the end of its cycle on N55 while the newer G-series cars moved to B58. So a 2019 X6 xDrive35i engine is an N55, not a B58, even though a 2019 X5 xDrive40i is a B58. Text your VIN and we will confirm which one your car carries.
Is the 2019 M4 engine an S55 or a B58?
S55. 2019 is the last full year of the F82 M4 and the F87 M2 Competition, both on the S55 M twin-turbo. The B58 in the M240i is a different engine entirely.
Do I need my VIN?
Yes — essential on 2019 BMW. The same displacement covers several engine families, and the chassis code plus pre- or post-LCI status decides harness and mounting fit. Text your VIN to +1-307-441-5554 and we will confirm the exact unit.
What is the warranty, and how fast does it ship?
A warranty is included on every 2019 unit and printed on the product page, with extended coverage up to 3 years available at checkout. Prep and ship is 3-5 business days, transit 2-3 business days after dispatch — typically 5-8 business days from order to delivery.

Our 6-Step Inspection & Shipping Process

Every 2019 BMW engine we ship has been through these six steps:

1. VIN-Matching
We match the donor VIN to your VIN to confirm engine code, chassis code, LCI status, and drivetrain fit.
2. Tested & Verified
ASE-certified technicians compression-test every cylinder and run leak-down evaluation on engines. Transmissions are Shift-Tested through all gears.
3. Noise & Smoke Verification
Units are run to verify normal mechanical sound and clean operation — catches internal wear static tests miss.
4. Visual Inspection
Every accessible component is inspected: turbos, manifolds, VANOS solenoids, oil-feed plumbing, accessories, sensor harnesses.
5. Photograph & Catalog
Multi-angle photos sent to you BEFORE we ship for your approval.
6. Palletize & Ship
Strapped on a heavy-duty wooden pallet, shipped via freight at no charge.

Our Photos-Before-Shipment Guarantee

Before any engine leaves our warehouse, we send you multi-angle photographs. You approve. If you do not approve, you get every dollar back — no questions, no restocking fees, no return freight charges. On top of 30-day money-back and the warranty included with every unit.
