When it comes to replacing a car part, choosing the right type can make a big difference in cost, performance, and reliability. The most common options include OEM (Original Equipment Manufacturer) parts, aftermarket parts, and salvaged or used parts. But which is best for your vehicle and budget?
At Select Auto Parts & Sales, we’ve guided thousands of Milwaukee drivers through this decision. Here’s a breakdown to help you choose the best fit for your car repair needs.
1. OEM Parts (Original Equipment Manufacturer)
What Are They?
OEM parts are made by the same manufacturer that built your vehicle—such as Honda, Ford, or Toyota. These parts match the exact specifications of the original components your car came with.
✅ Pros:
- Perfect fit — Designed to match your car precisely, with no need for modifications.
- Factory-grade quality — Meets the highest standards for safety and performance.
- Manufacturer warranty — Often includes 1–2 years of coverage.
❌ Cons:
- More expensive — Can cost 2–3 times more than aftermarket alternatives.
- Limited availability — Usually need to be ordered through authorized dealerships.
Best For:
- Newer vehicles still under warranty
- Critical systems such as airbags, sensors, ECUs, or steering components
2. Aftermarket Parts (Third-Party Manufacturers)
What Are They?
Aftermarket parts are made by independent companies like ACDelco, Denso, or Bosch—not your car’s original automaker.
✅ Pros:
- More affordable — Often 30–50% less expensive than OEM.
- Plenty of variety — From budget to premium performance parts.
- Widely available — Sold at most auto parts retailers and online.
❌ Cons:
- Quality varies — Some brands produce high-quality parts; others may cut corners.
- Fit may require adjustments — Slight differences in design can affect installation.
Best For:
- Older vehicles where OEM isn’t cost-effective
- Non-essential systems like filters, alternators, brake pads, or lights
3. Salvaged (Used) Parts
What Are They?
Salvaged parts are recycled from junked or wrecked cars. At Select Auto Parts & Sales, we professionally inspect and stock only reliable used parts.
✅ Pros:
- Most budget-friendly — Can save you 70–90% off the OEM cost.
- Environmentally responsible — Reuses functioning components and reduces landfill waste.
- Great for rare/discontinued vehicles — Hard-to-find parts become accessible.
❌ Cons:
- No or limited warranty — Unless the seller offers one.
- Unknown history — Previous wear and tear could lead to earlier failure.
Best For:
- Cosmetic or non-critical repairs — Like fenders, doors, mirrors, trim pieces
- Older cars where brand-new parts don’t make sense financially
