What affects the price

- OEM vs aftermarket brand
- Amperage rating and fitment for the engine
- Vehicle trim and production year specifics
- Core charge and return policy
- Warranty length and retailer support
Understanding these factors helps you compare quotes accurately and decide whether a refurb or new unit makes more sense for your budget and reliability needs.
Where to shop and how to verify compatibility
Shop around at both traditional retailers and online catalogs to find prices, availability, and warranty terms. Always verify the part number against your VIN and the drivetrain configuration to ensure compatibility.
