Get the best deals and discounts on used engines and restore your ride with confidence!
A used Kia Optima engine will fit any vehicle that came factory-equipped with that specific engine code and configuration. This typically covers Optima model years from 2011 through 2020, though fitment depends on your exact trim level and production date. Before we ship anything out, our team performs a VIN verification to confirm the engine you’re ordering is the correct match for your specific vehicle. This step matters — even within the same model year there can be differences in engine mounts, sensors, and accessory configurations that affect how the swap goes. We take that extra step so you’re not stuck with a part that doesn’t fit.
If you’ve already gotten quotes on rebuilding your current engine, you know it can get expensive fast — and that’s assuming the machine shop finds no surprises once it’s torn down. A used OEM Kia Optima engine gives you a complete, assembled unit with known mileage that’s ready to drop in, which saves you both time and money compared to a rebuild. You’re restoring factory performance rather than hoping a rebuilt engine holds up over time. For most vehicle owners and mechanics, swapping in a tested used engine is simply the smarter call. It’s faster, the pricing is predictable, and you’re working with original Kia engineering rather than aftermarket components.
Every used Kia Optima engine we sell comes with up to a 90-day warranty so you have some peace of mind after installation. Shipping typically takes 2–5 business days depending on your location, and we work to get orders out promptly. Please note that installation is not included, but if you need help locating a qualified mechanic or shop near you, we’re happy to point you in the right direction. These engines are genuine Kia OEM units, and we stand behind the quality of what we sell.
