A remanufactured engine is a used engine that has actually been totally taken apart, cleaned up, and examined. Any worn parts are replaced with brand-new components, and the engine is machined to meet original equipment manufacturer (OEM) specifications.

  • Pros: Often equivalent from new performance-wise, normally includes a multi-year warranty, more affordable than brand-new.
