Typically, replacing the throttle body on a Chrysler 300 costs roughly $350 to $800 in total, depending on parts and labor, with regional pricing and model-year variations.
In this article, we break down what drives that price, including parts options (OEM versus aftermarket versus remanufactured), labor times, diagnostic needs, and other potential charges. The goal is to help you plan a fair estimate whether you’re shopping around or preparing for a shop visit.
Cost breakdown
To understand the total bill, it helps to separate what you’re paying for: parts and labor (plus any add-ons). The following lists outline typical price ranges and common charges you might encounter.
Parts cost
- OEM Mopar throttle body for Chrysler 300 (3.6L or applicable engine): typically $350–$600
- Aftermarket throttle body (brands like Delphi, Dorman, etc.): typically $180–$350
- Remanufactured throttle body: typically $120–$250
- Gasket kit, seals, and any sensors required with installation: typically $20–$60
Prices vary by model year, engine type, and supplier. OEM parts are usually more expensive but offer guaranteed compatibility, while aftermarket or remanufactured units can provide substantial savings with reliable performance.
Labor and additional costs
- Labor time: typically 1 to 2 hours for a straightforward replacement; 2 to 3 hours for tougher access or older models
- Labor rate: commonly $85–$150 per hour, depending on region and shop
- Diagnostic and reprogramming fees: often $0–$100, depending on whether the shop performs recalibration or checks for related codes
- Core charge for remanufactured units: typically $50–$100, refundable upon returning the core
- Additional costs: intake duct seals, clamps, or mounting hardware if needed
Labor costs can swing based on regional rates, the engine variant, and how accessible the throttle body is on a given Chrysler 300 model year. Some shops may bundle diagnostic work into the replacement, while others itemize it separately.
What to know before you replace
Signs of a failing throttle body—such as rough idle, Check Engine Light with throttle-related codes, misfires, or poor acceleration—prompt the replacement decision. Some issues are caused by dirty throttle bodies that can be cleaned rather than replaced, which can reduce costs. Always confirm with a qualified technician whether cleaning is a viable first step before committing to a replacement.
When planning your repair, consider the engine type (3.6L Pentastar is common in many Chrysler 300s, but earlier or high-performance variants used different engines), the availability of remanufactured or aftermarket units in your region, and whether your vehicle requires programming or sensor recalibration after installation.
Saving money and buying tips
To keep costs in check, request quotes that clearly separate parts, labor, and any diagnostics, and ask about core charges and return policies on remanufactured units. Compare OEM versus aftermarket options and check whether the price includes necessary gaskets and recalibration. Some shops offer bundled service packages or promotions that can reduce the overall price.
Summary
For a Chrysler 300, a throttle body replacement typically runs about $350 to $800 total, with parts accounting for roughly $180 to $600 and labor adding roughly $100 to $350, depending on part choice, engine type, and local labor rates. OEM parts tend to cost more, while remanufactured or aftermarket units offer potential savings. Always confirm whether recalibration or related diagnostics are included in the quoted price and consider whether cleaning might solve the problem before proceeding to replacement.
