Prices for a throttle body on a 2010 Impala typically range from about $120 to $500, depending on whether you buy a new OEM part, a remanufactured unit, an aftermarket option, or a used component. Labor costs, if you hire a mechanic, will add to the total.
The 2010 Chevrolet Impala uses an electronically controlled throttle body as part of GM’s drive-by-wire system. Availability and pricing vary by engine option (for example, some trims used a 3.5-liter V6 and others had different configurations), so it’s important to verify the exact part number that fits your VIN. If you’re unsure, consult a parts specialist or a technician to ensure compatibility and proper programming if required.
Price ranges by condition
Below is a snapshot of typical price ranges from common sources. Actual prices can vary by retailer, location, and the specific engine variant of your Impala.
- New OEM throttle body (GM/Delco) — roughly $350–$550. Dealer pricing is often at the higher end of this range.
- Remanufactured throttle body — roughly $120–$250, usually with a limited warranty.
- Aftermarket / brands like Dorman or other suppliers — roughly $120–$320, offering a balance of price and compatibility.
- Used or salvage-yard throttle body — roughly $50–$150, with heightened risk of wear or unknown history.
Prices can fluctuate based on supplier and region, and some vendors may include shipping or core charges. It's also wise to confirm whether the unit requires programming or calibration after installation, which can affect overall cost.
Where to buy
Below are common avenues to purchase a throttle body for a 2010 Impala. Each option has its own advantages and caveats in terms of price, warranty, and fit.
- Authorized GM dealers and GM Parts websites — best for genuine OEM parts and exact VIN compatibility, but typically the most expensive option.
- Major auto parts retailers (AutoZone, Advance Auto Parts, O'Reilly) — wide selection of OEM, remanufactured, and aftermarket parts with store pickup or delivery and warranties.
- Online marketplaces (Amazon, eBay) — often the broadest price range; verify fit by engine code and confirm seller reliability and return policy.
- Salvage yards and used-parts suppliers — lowest upfront cost; ensure part is clean, undamaged, and compatible with your engine and VIN.
When purchasing, always confirm the exact part number for your vehicle’s engine and VIN. If you’re replacing an electronic throttle body, be prepared for potential programming or calibration steps, which may require professional service or specialized equipment.
Summary
For a 2010 Impala, the throttle body price spans from about $120 to $500 depending on condition and source, with labor costs adding to the total if you’re not performing the replacement yourself.
