This fits the following vehicles:

• 1999 Ford Mustang GT 4.6 Vin X

Engine fitment can be verified with the notes and ‘Vehicle Fitment’ tab above, or with the casting numbers under ‘Additional Information’ (if applicable).

Every engine we sell is fully remanufactured to meet or exceed OEM specifications:

• Deep Clean – To start the remanufacturing process, every engine is fully disassembled and hot tanked (cast iron) or thermally cleaned (aluminum)
• Inspection – Magnaflux testing uses magnetic particles to inspect metal, checking for microscopic cracks and fissures that will cause long-term failure. All parts are visually inspected as well.
• Machining and New Parts – Deck surfaces are CNC machined and new parts are added. New parts include bearings, pistons, rings, lifters, oil pump, gaskets, Viton™ valve seals, freeze plugs, galley plugs and either a new timing chain (with new tensioners) or a new timing belt (with new tensioner). If an engine has a timing-driven water pump, a new pump is installed.
• SIM Testing – Each engine is SIM tested after reassembly, with the cooling and oil systems being fully pressurized and the crank being spun at high RPM to verify compression and build quality.

Because of our rigorous remanufacturing process, we can offer the industry’s best warranties. Each engine comes with up to 7 years and 1 million miles of warranty, which can be upgraded to include Pure Care™ no-fault protection. No other engine manufacturer comes close.

Frequently Asked Questions

1. Is this engine a direct replacement for all 1999 Mustangs?

It fits 1999 Mustang GT models equipped with the 4.6L VIN X engine.

2. Does this require ECU tuning?

No ECU reprogramming is required when replacing the same VIN X configuration.

3. Is this the same as the DOHC Cobra engine?

No. This is the 2-valve SOHC configuration. Cobra models use a DOHC design.

4. Why choose remanufactured instead of used?

Remanufactured engines restore internal tolerances and replace worn components, reducing reliability risks.

5. Is this suitable for daily driving?

Yes. It is built to restore factory drivability and smooth performance.

6. Can repair shops purchase this engine?

Yes. It is suitable for professional installation in 1999 Mustang GT models.
