How Much Does a Car Injector Cost?

As of 2025, a single fuel injector typically costs $50–150 for a gasoline port-injected engine, $150–400 for gasoline direct injection (GDI), and $250–700 for common-rail diesel; installed costs per injector usually run $250–650 (port), $450–1,000 (GDI), and $450–1,200 (diesel), with full set replacements ranging roughly from $600–2,500 for many gas cars to $2,500–6,500 for modern diesel trucks. Prices vary by vehicle, brand (OEM vs aftermarket), and labor time.

What Determines Injector Price

Fuel injector pricing depends on technology, brand, and how difficult the parts are to access. GDI and diesel systems operate at far higher pressures and tighter tolerances than older port-injected systems, so they cost more and often require extra parts and procedures during replacement.

The following list outlines the major factors that drive injector costs.

• Fuel system type: Port injection is least expensive; GDI is mid-to-high; common-rail diesel is highest.
• OEM vs aftermarket: OEM parts often cost 20–100% more than reputable aftermarket brands; remanufactured units can save 25–50% if sourced from a trusted rebuilder.
• Vehicle make/model: European brands and some turbocharged or luxury applications often have pricier, coded injectors.
• Labor time and access: Manifold removal, high-pressure lines, and tight engine bays increase labor hours.
• Required ancillaries: New high-pressure lines (single-use on many GDI/diesels), seals, rails, filters, and coding/programming add cost.
• Supply and demand: Popular truck diesels (Duramax, Power Stroke, Cummins) see higher part costs; availability can shift pricing.

In practice, the mix of system type, parts source, and labor complexity explains most of the price spread you’ll see on estimates.

Typical Price Ranges by System

Gasoline Port Injection (PFI)

Parts: $50–150 per injector (aftermarket), $100–300 (OEM). Installed per injector: $250–650, depending on access and labor rates. Full set (4–8 injectors): $400–1,200 parts; $600–2,500 installed.

Gasoline Direct Injection (GDI)

Parts: $150–400 per injector (Bosch/Denso/Delphi units are common). Installed per injector: $450–1,000. Full set (4–8 injectors): $900–3,200 parts; $1,200–4,500 installed. Many GDI jobs also require single-use high-pressure lines at $15–45 each and new seals.

Common-Rail Diesel

Parts: $250–700 per injector (often Bosch, Denso, Siemens/Continental). Installed per injector: $450–1,200. Full set (6–8 injectors): $1,500–5,600 parts; $2,500–6,500 installed. High-pressure lines can add $30–90 each; some sets require rails or return lines and injector coding.

Real-World Installed Cost Examples

The examples below illustrate typical U.S. shop pricing with labor rates around $95–180 per hour, recognizing that local markets and specific trims can shift totals.

Here are representative ranges for common vehicles.

• 2015 Toyota Camry (2.5L port injection): $80–140 per injector; 1.5–2.0 hours labor for one. One injector installed: $250–500; full set: $700–1,400.
• 2018 Ford F-150 3.5L EcoBoost (GDI): $170–280 per injector; 3–4 hours labor for a set due to access. One injector installed: $500–850; full set (6): $1,500–2,400.
• 2020 VW/Audi 2.0T (GDI, coded): $200–350 per injector; coding may add $50–150. One injector installed: $600–1,000; full set (4): $1,400–3,000.
• 2017 Chevy Silverado 2500 6.6L Duramax (diesel): $350–500 per injector; 6–10 hours labor for set; new lines recommended. One injector installed: $600–1,100; full set (8): $3,800–6,500.

These figures assume no additional repairs. Contamination, seized hardware, or rail/line replacement can raise totals.

Beyond the Injector: Extra Costs to Expect

Injector jobs often involve other parts and procedures that protect the new components and ensure proper operation, especially in high-pressure systems.

The following bullet points summarize common add-ons and their typical costs.

• High-pressure fuel lines: Single-use on many GDI/diesel systems; $15–45 each (GDI), $30–90 each (diesel).
• Seals, O-rings, filters, and clips: $10–60 per cylinder depending on kit quality.
• Fuel rail or return lines: $100–400 if required or damaged.
• Coding/programming (BMW, Mercedes, VW/Audi, some Fords): $50–200.
• Diagnostics and leak-down/flow testing: $100–200 prior to replacement.
• Fuel system cleaning after failure: $30–150 for additive/service; more if tank/lines are contaminated.

These costs are not universal but are common enough to appear on many estimates; they help prevent early failure of new injectors.

Replace One Injector—or All?

Whether to replace a single injector or a complete set depends on age, mileage, and failure mode. On newer vehicles with a clear single-injector fault, replacing just the bad unit is often sensible. On high-mileage GDI or diesel engines—especially with contamination—many technicians recommend replacing the set to avoid repeated labor.

Can Cleaning Save Money?

If an injector is clogged rather than electrically failed or leaking, professional cleaning and flow-testing can be cost-effective. This is more successful on port-injected gas engines and less so on severely worn GDI or diesel units.

Consider these common service options and what they cost.

• On-car cleaning (induction/fuel-rail service): $80–150; helpful for mild deposits but won’t fix a stuck or leaking injector.
• Bench ultrasonic cleaning with flow test: $20–35 per injector plus a setup fee ($40–80); can restore spray patterns and balance.
• Injector refurbishment/exchange (diesel/GDI): Often saves 25–40% vs new; seek shops that provide test data and warranty.

Cleaning makes sense when diagnostics point to clogging; if internal wear or electrical faults exist, replacement is the durable fix.

Symptoms and Diagnosis

Bad injectors can mimic ignition or compression problems. Proper diagnostics helps avoid unnecessary parts replacement.

Watch for the following signs before committing to a replacement.

• Rough idle, misfires under load, poor fuel economy, or hard starts.
• Fuel smell, black smoke (rich), white smoke/diesel knock (diesel over-fueling), or elevated short/long-term fuel trims.
• Trouble codes: P02xx series (cylinder contribution, injector circuit), lean/rich codes.
• Balance tests, return-flow (diesel), and injector disable tests indicating a weak cylinder.

A shop that confirms the root cause—electrical vs mechanical vs contamination—can quote accurately and prevent repeat visits.

How to Budget and Save

With wide price ranges, a systematic approach helps control costs while maintaining reliability.

Follow these steps to estimate and manage your injector spend.

1. Confirm diagnosis with scan data and tests; avoid guessing based on a single code.
2. Get two to three quotes that break out parts, labor hours, and any required lines/seals/coding.
3. Choose parts wisely: OEM or high-quality aftermarket for gas; OEM/new or reputable reman with test sheets for diesel.
4. Ask about related maintenance: new fuel filter, oil change (if fuel diluted), and intake valve cleaning for GDI.
5. Check warranty terms: 12–24 months on new parts is common; verify labor warranty as well.

This approach can trim hundreds of dollars and reduce the chance of repeat failures, especially on GDI and diesel systems.

Regional and Market Notes

Prices here are in U.S. dollars. Labor rates and parts pricing vary by region; urban areas and dealer service departments tend to charge more. For a quick local sanity check, multiply labor hours by your local shop rate and add the parts figures that match your system type.

Bottom Line

Expect $50–150 per injector for port-injected gas engines, $150–400 for GDI, and $250–700 for diesel, with installed costs per injector ranging roughly from $250–1,200 depending on system and access. Full sets and high-pressure systems drive the total into the thousands, especially on modern diesels. A precise estimate hinges on accurate diagnosis, the vehicle’s fuel system, and whether ancillary parts and coding are required.

Summary

Fuel injector pricing varies widely by technology and vehicle. Most gas port injectors are affordable; GDI and diesel injectors are costlier and often require extra lines, seals, and coding. Installed, plan for $250–650 per injector on port-injected engines, $450–1,000 on GDI, and $450–1,200 on diesel, with full-set replacements ranging from roughly $600–2,500 (many gas cars) to $2,500–6,500 (diesel trucks). Careful diagnosis, quality parts, and a clear breakdown of labor and add-ons are key to an accurate, fair quote.

Is it worth replacing a fuel injector?

Yes, it is worth replacing fuel injectors if they are failing, as this can improve engine performance, fuel efficiency, and overall truck health, while preventing further engine damage. However, replacing fuel injectors is usually a necessity for continued driving rather than a beneficial upgrade, and the decision to replace them should be based on professional diagnosis of issues like engine misfires, reduced fuel efficiency, or engine damage from leaks. 
Signs You Need to Replace Your Fuel Injectors

• Misfiring Engine: Opens in new tabA faulty injector can cause uneven fuel delivery, leading to an engine that misfires or idles roughly. 
• Reduced Fuel Efficiency: Opens in new tabWhen injectors don’t deliver fuel correctly, the engine cannot combust fuel efficiently, leading to lower MPG. 
• Fuel Leaks: Opens in new tabLeaking injectors can cause excess fuel to enter the engine, which is inefficient and can lead to potential engine damage. 
• Hard Starting or Stalling: Opens in new tabInsufficient fuel delivery from a faulty injector can make the engine difficult to start or cause it to stall. 

Benefits of Replacement

• Improved Engine Performance: New injectors ensure accurate fuel delivery, resulting in better acceleration, smoother idling, and faster throttle response. 
• Increased Fuel Efficiency: Correctly atomized fuel combusts more completely, leading to better gas mileage. 
• Extended Engine Life: By ensuring efficient combustion and balancing fuel delivery to each cylinder, new injectors reduce engine strain and extend its life. 
• Reduced Emissions: Complete fuel combustion leads to fewer unburnt fuels being expelled, which reduces harmful vehicle emissions. 

When to Replace

• Failure Detection: It’s crucial to replace a fuel injector immediately if a professional diagnoses a failing injector. 
• Preventative Maintenance: For preventative maintenance, some recommend replacing fuel injectors every 50,000 to 100,000 miles, though this can vary based on vehicle condition and driving habits. 
• Consider Replacing All at Once: Replacing all injectors at the same time can prevent future headaches from multiple failures and ensure even fuel delivery across all cylinders.
