How much does it cost to replace fuel injectors on a Honda Fit?

Replacing all four fuel injectors on a Honda Fit typically runs about $400 to $900, depending on the injector type (OEM vs aftermarket) and local labor rates. If only a single injector is faulty, the bill will be smaller, but in the Fit’s four-cylinder engine, most shops recommend replacing all four for reliability and warranty reasons.

Cost drivers

Several factors determine the final price when replacing fuel injectors on a Honda Fit. The engine used in the Fit is a four-cylinder 1.5-liter, which means four injectors are involved. Costs hinge on the parts chosen, the amount of labor required, and any additional services or shop fees.

• Parts cost: injector price varies by brand and quality. New OEM-style injectors typically range from about $60 to $120 each, while aftermarket or remanufactured injectors can be cheaper, roughly $20 to $60 per unit. Replacing all four injectors thus commonly totals around $240 to $480 for parts when using OEM or higher-quality aftermarket units.


• Labor cost: labor time for injector replacement on a Honda Fit generally falls in the 2 to 4 hour range, depending on engine access and shop workflow. With typical labor rates between $75 and $125 per hour, labor can run about $150 to $500.


• Additional parts and fees: new O-rings or seals, a possible fuel rail gasket, and a diagnostic check can add $20 to $60 or more. Some shops also add disposal or shop supply fees.


• Optional services: fuel system cleaning or injector testing/flow matching can add to the cost, though these are not always necessary if injectors are replaced with new units.


• Regional variation: prices can differ significantly by region, vehicle shop, and whether you choose dealership, independent shop, or national chain service.

These factors combine to produce the final bill, which can vary widely from one job to the next.

Typical total cost scenarios

To give a sense of what customers might expect, here are common scenarios for a Honda Fit with four injectors. Use these as a rough guide when budgeting for the repair.

• Full four-injector replacement with aftermarket/remanufactured injectors: Parts $80–$240, Labor $150–$400, plus minor fees. Total commonly $230–$700.


• Full four-injector replacement with OEM-equivalent injectors: Parts $240–$480, Labor $200–$450, plus minor fees. Total commonly $440–$900.


• Single-injector replacement (if only one injector is faulty) with labor proportional to time: Parts $60–$120, Labor $75–$200. Total commonly $150–$320.

Note that many independent shops prefer to replace all four injectors during a single service to ensure uniform performance and protect against future failures, which can influence the final cost.

What to expect by model year

Early to mid-generation Fits (roughly 2007–2014)

These models use a 1.5-liter inline-four engine with four injectors. Prices are generally in the typical ranges described above, with labor time being fairly standard for an injector replacement, though access and condition of the fuel rails can affect duration.

Later-generation Fits (roughly 2015–2020/2021)

Later Fits maintain the same basic injector count and layout, so the cost framework remains similar. Some newer models may benefit from updated fuel-injection hardware, but the overall price bands—parts versus labor—remain in the same range, with regional differences driving the final total.

Tips for getting an accurate quote

To avoid surprises, ask for a written estimate that itemizes parts, labor, and any additional fees. Consider requesting the following:

• Breakdown of four injectors by part number and price (OEM vs aftermarket).


• Estimated labor hours and hourly rate, plus expected total labor time.


• Costs for O-rings, seals, and any necessary fuel system diagnostics.


• Any optional services (e.g., fuel system cleaning) and their cost, plus their necessity for your vehicle’s condition.


• Warranty terms on parts and labor.

Comparing quotes from multiple shops can help ensure you get a fair price and avoid surprises at the counter.

Summary

For a Honda Fit with a four-cylinder 1.5-liter engine, replacing all four fuel injectors typically costs between $400 and $900, depending on injector quality, labor rates, and any optional services. Replacing a single failing injector is cheaper but not always advisable if others show wear. Always obtain a detailed, written estimate that separates parts, labor, and fees, and consider the long-term reliability and warranty when choosing between OEM and aftermarket injectors.

Can you drive a car with a bad injector?

No, it is not recommended to drive with a bad fuel injector as it can lead to various issues, from poor performance to severe engine damage and safety hazards. The most significant risks include engine misfires, a damaged catalytic converter, and potentially catastrophic engine failure like hydrolocking, so it is best to get the vehicle inspected and repaired immediately.

Risks of driving with a bad fuel injector

• Poor engine performance: You may experience engine misfires, stalling, and a decrease in fuel efficiency. The engine may also feel rough and vibrate. 
• Damage to other components: An incorrect air-fuel mixture can cause the catalytic converter to overheat and fail, which is an expensive repair. Driving with a leaking injector can also dilute the engine oil. 
• Catastrophic engine damage: If an injector leaks too much fuel, it can cause the engine to hydrolock. This occurs when liquid fuel fills the cylinder, and because liquids are incompressible, it can lead to bent connecting rods and other severe internal engine damage. 
• Safety concerns: External fuel leaks from a bad injector can create a fire hazard. 

What you should do instead

• Avoid driving the vehicle if possible. 
• If you must drive, do so for the shortest distance necessary to get to a repair shop. 
• Have the car inspected and repaired by a professional mechanic as soon as possible to prevent further damage.
