Replacing all four fuel injectors on a 2019 Honda Accord typically costs between $800 and $1,300, depending on engine variant, injector pricing, and local labor rates. Replacing only one injector or opting for a cleaning service can fall outside this range.
Cost overview
The following breakdown covers the main expense categories you’re likely to encounter when replacing all four injectors on a 2019 Accord.
- Parts: four fuel injectors (OEM or aftermarket), plus seals, O-rings, and related hardware
- Fuel-system components: gaskets, rail seals, and any necessary connectors
- Optional items: wiring harness connectors or sensors if replaced during the job
Costs can vary based on whether you choose OEM Honda injectors or reputable aftermarket equivalents, and whether the shop uses new seals and gaskets or reuses old ones.
Labor and time
Labor is a major portion of the total because replacing four direct-injectors can involve removing parts of the intake or fuel system to access the injectors, plus reuse or replacement of seals.
- Estimated time: roughly 3 to 6 hours, depending on engine variant (1.5L or 2.0L turbo) and whether the intake manifold must be removed
- Labor rate: commonly between $75 and $150 per hour, depending on location and shop
In many markets, the total labor cost falls toward the middle or upper end of the range due to the complexity of direct-injection systems on modern Hondas.
Other considerations and potential costs
Beyond the core injector replacement, several ancillary costs can appear on a bill. These figures illustrate typical possibilities.
- Diagnostics and inspection: $50–$120 to confirm misfire codes and injector operation
- Core charges and returns: some shops assess a core charge if injectors are ordered as a set; credits apply when cores are returned
- Taxes, shop supplies, and disposal fees: commonly 5–10% of parts/labor or a small fixed fee
- Cleaning vs replacement: if carbon buildup or deposits are extensive, cleaning or additional services may be recommended, affecting overall cost
Actual final pricing depends on your vehicle’s exact engine, local labor rates, and the shop’s pricing policies for OEM versus aftermarket parts.
Factors that affect price
- Engine variant: 1.5L turbocharged vs. 2.0L turbo may influence access and service steps
- Injector type: direct-injection injectors tend to be more expensive than some port-injection equivalents
- Parts choice: OEM Honda injectors typically cost more than aftermarket options
- Labor complexity: optional intake manifold removal or additional repairs increases hours
- Geographic location and shop rate: urban areas or dealer service centers usually charge more
Understanding these factors can help you set expectations and compare estimates from different shops.
What to ask your shop
- Do you replace all four injectors or only those failing tests indicate?
- Are OEM injectors required, or are high-quality aftermarket injectors acceptable?
- Is there a warranty on parts and labor, and what does it cover?
- Will the job include new seals, O-rings, and any necessary gaskets?
- Is diagnostic testing included in the estimate, or billed separately?
- Can you provide an itemized estimate with parts, labor, and any potential core charges?
Getting a written, itemized quote helps you compare apples to apples and understand where costs come from.
Summary
For a 2019 Honda Accord, replacing all four fuel injectors typically falls in the $800–$1,300 range, with broader swings based on engine variant, parts choice, and local labor rates. If carbon buildup or related issues are present, cleaning or additional repairs may alter the total. Always obtain an itemized estimate and ask about warranties to ensure you’re paying for a durable, properly installed solution.
Note: Prices vary by region, shop, and whether the injectors are OEM Honda parts or aftermarket equivalents. The figures above reflect common market ranges as of 2024–2025 and are intended as a guide rather than a guaranteed quote.
