Prices vary by engine, year, and whether the part is new, used, or aftermarket. In general, you’ll pay roughly $80 to $700 for a throttle body on a Chevy Impala, with common new OEM units in the $180–$350 range and higher for the V8 Impala SS. This guide breaks down the factors and current ranges to help you shop.
What affects the price
Several factors determine how much a throttle body for the Impala costs, including engine type, part condition, and where you buy it.
- Engine type and model year: Impalas with the 3.8L (3800) V6 use a different throttle body than the 5.3L V8 in the Impala SS, and prices reflect that difference.
- Part condition: new OEM vs rebuilt/remanufactured vs used from a salvage yard will have different price points.
- Source and brand: dealer/GM parts tend to be more expensive than aftermarket brands or online retailers; availability and brand (Delphi, Bosch, Dorman, ACDelco, etc.) affect price.
- Inclusions and compatibility: some throttle bodies come with sensors or gaskets; some require a throttle adaptation or re-learn procedure after installation.
- Shipping, taxes, and location: online purchases add shipping, while local taxes vary by region.
In short, price variability is driven by engine application, condition, and where you shop.
Typical price ranges by configuration
To help you shop, here are representative price ranges you’ll see for common Impala configurations.
- New OEM throttle body for 3.8L V6 (1997–2005): typically $180–$350
- New OEM throttle body for 5.3L V8 (Impala SS, 2004–2005): typically $350–$700
- Aftermarket throttle bodies (brands compatible with Impala engines): typically $120–$350
- Used or remanufactured units (salvage yards or online sellers): typically $80–$200
Overall, the 3.8L models tend to sit at the lower end of the spectrum, while the high-performance SS models push toward the higher end. Availability can also affect pricing.
OEM vs aftermarket considerations
Choosing between OEM and aftermarket parts impacts price and compatibility. OEM throttle bodies are designed for your exact engine and vehicle, and may include the original sensors. Aftermarket units can save money but require careful verification for fitment and may require a re-learn procedure.
Where to buy and how to check compatibility
Shop with an eye toward part number compatibility, VIN, and return policies. Common sources include:
- GM dealership or official GM parts retailers
- Online auto parts retailers (RockAuto, AutoZone, O'Reilly)
- Local salvage yards and rebuilt-parts shops
- General marketplaces with caution (verify part numbers and warranty)
Always verify the exact throttle body part number for your Impala’s year, engine code, and VIN before purchasing, and confirm whether a re-learn is required after installation.
Installation and labor considerations
Replacing a throttle body is usually accessible to a DIYer with basic tools, but labor costs vary by region and shop rates. Expect roughly 1–3 hours of labor, plus any diagnostic time if a re-learn is needed. When in doubt, a professional installation can ensure proper calibration and performance.
Summary
For a Chevy Impala, throttle body prices range from about 80 to 700, depending on model and condition. Plan roughly $180–$350 for a new OEM 3.8L unit, with higher prices for 5.3L V8 SS models. Used or aftermarket parts are typically cheaper, and installation costs add to the total. Always verify compatibility with your exact year, engine, and VIN, and consider whether a re-learn procedure is required after installation.
