For a 2018 Honda Accord, fuel injectors cost roughly $50–$180 each when new from OEM or aftermarket suppliers; a full set of four typically runs about $200–$700, depending on brand and source. Labor and related parts can add to the total if you’re having them replaced.
To understand this question in more detail: the 2018 Accord offers two engines—a 1.5-liter turbo and a 2.0-liter turbo—each using four fuel injectors. Prices vary by whether you buy new OEM, aftermarket, remanufactured, or used, and by where you purchase them. The answers below lay out typical price ranges, buying sources, and installation considerations as of 2026.
Price ranges by source
Below are the typical price ranges you can expect for a single injector and for a full set, depending on the source. Prices fluctuate with market conditions and availability.
- OEM/new injectors from a Honda dealer: approximately $90–$160 per injector; full set roughly $360–$640.
- Aftermarket new injectors (brands like Denso, Hitachi, Bosch, Standard Motor Products): about $40–$100 per injector; full set around $160–$400.
- Remanufactured/rebuilt injectors: typically $60–$120 per injector; full set about $240–$480.
- Used/ salvaged injectors: roughly $20–$60 per injector; full set around $80–$240.
In conclusion, you have a wide price band depending on whether you prioritize OEM assurance, the lowest upfront cost, or a middle-ground option with remanufactured units. The total for four injectors will vary accordingly.
OEM vs aftermarket considerations
Choosing between OEM and aftermarket injectors affects price, warranty, and compatibility. OEM injectors typically carry the strongest warranty and guaranteed compatibility with Honda systems but come at a premium. Aftermarket injectors can save money but may vary in long-term reliability and may require careful brand selection to ensure proper fit and performance.
Where to buy
Where you purchase injectors can influence price and service options, including warranties and return policies. The following sources are commonly used by buyers of a 2018 Honda Accord injectors.
- Honda dealership parts departments (OEM): official pricing, guaranteed compatibility, and warranty.
- Auto parts retailers (in-store or online): AutoZone, Advance Auto Parts, O'Reilly; a mix of OEM and aftermarket options.
- Online marketplaces and auto parts specialists (RockAuto, Amazon, eBay Motors): wide range of brands and prices; pay attention to seller reliability and return policies.
- Salvage yards and junkyards: lowest upfront price for used injectors; variable reliability and limited or no warranty.
Prices and availability vary by location and seller. It’s wise to compare several sources and check return policies and warranties before buying.
Labor and installation considerations
Replacing fuel injectors is a job that often requires professional service to ensure proper sealing, fuel system pressure, and engine timing. Here are typical expectations for labor and related costs.
- Labor time: about 2–4 hours for a four-injector job on a 2018 Honda Accord, depending on engine variant and accessibility.
- Labor rate: commonly $75–$150 per hour at independent shops; higher in urban areas or at dealerships.
- Additional costs: new injector O-rings, fuel rail seals, a potential fuel filter replacement, and hub or intake manifold gasket if disturbed.
- Estimates: all-in, you might see roughly $300–$900 in labor and parts (excluding tax) for a full injector replacement at a shop, depending on parts chosen and local rates.
Getting a precise quote requires a diagnostic check and confirming the specific engine variant (1.5L vs 2.0L) and whether any ancillary parts are needed. Ask the shop for a line-item estimate before work begins.
Notes and diagnostic considerations
Injector problems can present as rough idling, misfires, or fuel smell. It’s important to diagnose accurately rather than replacing injectors as a first step. A professional shop can perform fuel-pressure tests, injector balance tests, and fault code checks (OBD-II) to confirm the root cause before you purchase parts.
Summary
For a 2018 Honda Accord, expect individual fuel injectors to cost about $50–$180 each when new, with a full four-injector set running roughly $200–$700 depending on OEM vs aftermarket sourcing. Prices vary by engine variant, and you’ll also need to consider labor costs (roughly $200–$900 for installation, depending on shop rates and complexity). Compare OEM, aftermarket, remanufactured, and used options, and obtain a precise quote that includes related parts and labor before proceeding.
Bottom line
Prices fluctuate, so check current listings from dealers and reputable retailers, and consult a qualified technician to confirm the exact injector type and replacement approach for your 2018 Honda Accord.
