How much does it cost to replace 1 injector?
Replacing a single fuel injector typically costs between $300 and $800 in the United States, including parts and labor. More advanced or premium systems can push toward $1,000 or more. This article breaks down the factors and provides typical ranges to help drivers budget.
The cost to replace one injector depends on engine design (port vs direct injection), the part brand, labor rates, and whether other components are involved in the repair. Below is a breakdown of typical costs and what influences them.
Port fuel injector: costs and timeline
Typical costs for port injectors include parts, labor, and related charges. Prices vary by OEM vs aftermarket and by vehicle model.
Overview of port injector pricing
- Parts cost: Port injectors (non-high-pressure) typically range from about $50 to $150 per injector when bought aftermarket; OEM equivalents commonly run $120 to $260 per injector, depending on brand and vehicle.
- Labor time: Expect about 1.5 to 3 hours of labor for access and replacement on most engines; more complex installations can approach 4 hours.
- Total ballpark: With diagnostic checks and any required O-rings or seals, a typical out-the-door price for replacing one port injector usually falls in the $200 to $600 range, with many common cars landing around $350–$550.
Port injector replacements are generally the least expensive scenario among injector replacements, though pricing can vary based on access and model.
Direct-injection injector: costs and timeline
Direct-injection injectors are high-pressure devices and can require more labor due to engine layout, which increases the price.
Overview of direct-injection pricing
- Parts cost: Direct-injection high-pressure injectors typically cost $180 to $450 per injector for common brands; some OEM units or high-performance variants can run $500–$700 per injector.
- Labor time: Replacing a direct-injection injector can require removing the intake manifold and fuel rail, typically about 3 to 5 hours; more complex engines can exceed 6 hours.
- Total ballpark: With diagnostic and ancillary parts, the price often ranges from roughly $500 to $1,000 or more for a single injector replacement, depending on model and region.
Direct-injection replacements tend to be significantly more expensive than port injectors due to higher part costs and longer labor.
Other costs and considerations
In addition to the injector unit itself and labor, you may encounter:
- Diagnostic fees: Some shops charge a diagnostic or fault-code reading fee, often $40 to $120, even if you proceed with the repair.
- Core charges and warranties: Some brands apply core charges or offer extended warranties; the core deposit is often refundable after the part is returned.
- Related parts and services: O-rings, seals, and fuel-line clamps, plus potential related components if the injector failure caused damage to the fuel rail or intake manifold gaskets.
- Potential safety/recall considerations: If your vehicle is under a manufacturer recall related to injectors, or if multiple injectors are affected, the shop may price differently or cover more of the cost under warranty or a campaign.
When budgeting, ask for a written estimate that separates parts, labor, diagnostic fees, and any possible additional work tied to your vehicle's condition.
Summary
Replacing a single fuel injector is typically a mid-range repair. Port injectors usually offer the most affordable path, with out-the-door pricing often in the hundreds of dollars. Direct-injection injectors drive costs higher due to expensive parts and longer labor. Always obtain multiple quotes and confirm what’s included in the estimate—parts, labor, diagnostics, and any related service—before authorizing the work. A measured approach helps ensure you’re not surprised by the bill and that the fix addresses the root cause of any drivability issues.
