How did we estimate these prices?

Jerry's experts researched and collected data from 2500+ real repair shops in all 50 states in the US, including everything from the total cost of repair services to the hourly labor cost for mechanic labor in each shop. We combined that data with our expert database of hundreds of real repair jobs, thousands of real cars, millions of real car part prices in order to best estimate the cost of each repair service. Our labor cost estimate is calculated by taking the average hourly labor rate for a certified mechanic in the US, times the number of hours it takes on average to complete a repair. We recommend you compare your local shops with Jerry and contact those shops directly to get final pricing for your vehicle.

What parts do I need for a fuel injector replacement and how much do those parts cost?

If you have a bad fuel injector that needs replacing, it’s generally the only part you’ll need to buy. However, some vehicles have multi-point fuel injection, where each cylinder has an injector, which is complex and expensive to replace. More commonly, cars will have a single-point injection or one injector for every two cylinders. 
The average cost to buy a replacement fuel injector is between $350 and $850 but can vary based on your vehicle's make and model. Smaller cars with fewer cylinders tend to have less expensive parts, while larger, high-performance engines have more.
On top of the fuel injectors, you’ll also need some basic tools for the replacement:
  • Fuel injector seals
  • Ratchet and socket set
  • Flathead screwdriver
  • Pliers
  • Towels or rags
If your fuel injector fails and your car is still under warranty, contact your local dealership to see if replacement is covered. If your local auto parts stores like AutoZone, Advance Auto Parts, and NAPA Auto Parts, as well as online retailers like Amazon and RockAuto. Some reputable brands we recommend are Bosch, Delphi, and Denso. However, like price, recommended brands may also vary depending on your vehicle’s specific year, make, and model.
Yes. If your fuel injectors are faulty, it can lead to excessive leaking, causing the fuel pressure to drop. Eventually, this can lead to reduced fuel efficiency and loss of engine power. If your injectors are faulty or damaged, you’ll want to replace them sooner rather than later.
Like many other car components, the fuel injectors eventually wear and need replacing. While aftermarket parts are okay for some replacements, replacing your fuel injectors with OEM parts is usually recommended, primarily because of their ability to communicate with the injector control module. Because they’re also built to your vehicle specifications, you know they will have the correct fit and mount, and you won’t have any issues with them down the road.
Fuel injectors are available through most auto parts shops like AutoZone, Advance Auto Parts and NAPA Auto Parts. You can also find them online through sites like Amazon and RockAuto. However, check with your owner’s manual to confirm they’re compatible with your car. If you’re looking for OEM parts, you may also be able to purchase them through your local dealership.

How will a mechanic replace my fuel injectors?

To replace your fuel injector, a mechanic will usually perform the following steps:
  • After the engine is cold, relieve pressure within the fuel rail
  • Remove any wiring, hoses, or cables that restrict access to the injector
  • Unbolt and remove the fuel rail
  • Remove the fuel injector from the rail
  • Reinsert the new (or repaired) fuel injector
  • Reinstall the fuel rail and reconnect all the cables, hoses, and wiring that were previously disconnected

What happens if I don’t replace my fuel injectors?

It’s technically safe to drive with a faulty fuel injector as long as there is no external leakage.
But you risk engine misfires, excessive emissions, or an overheated catalytic converter if you continue driving with a broken or malfunctioning fuel injector.

What is a fuel injector?

Fuel injectors are critical to your car’s engine and fuel system. They’re designed to deliver fuel into the car’s engine via electronically controlled valves. The injectors have an atomizing nozzle that distributes the right amount of fuel for optimum combustion and efficiency. 
Most cars have one fuel injector per cylinder, so a four-cylinder car usually has four fuel injectors for optimal fuel delivery.
When you take your car for a fuel injector replacement or service, a mechanic will remove your car’s fuel rail, replace the defective fuel injector with a working one, and run the engine to check there are no leaks.
The fuel injectors provide the correct amount of fuel to the engine so that it can efficiently generate power. They can deteriorate and break down over time, resulting in fuel leaks.

How do I know if my fuel injectors need replacing?

The following are some of the most common signs of a bad fuel injector:
If you’re undergoing any major repairs and your engine is disassembled, that’s the perfect time to have your fuel injector inspected and serviced!

How often should you change your fuel injectors?

In most cases, fuel injectors should be replaced every 50,000 to 100,000 miles. This is based on multiple factors, so some cars may have a shorter or longer duration before replacing their injectors. 
However, while you may not need to replace your fuel injectors often, you should have them cleaned more frequently. It’s recommended to have your fuel injectors cleaned every 36 months or 45,000 miles, whichever comes first. Following a regular maintenance schedule and cleaning them can help prolong their lifespan. 

Can I replace the fuel injectors myself?

If you’re car-savvy and have experience working with automotive repairs or replacements, you might be able to change your fuel injectors yourself. Be mindful that if you change your fuel injectors, you’ll want to change them all. Pairing new injectors with old ones can lead to inconsistent performance and a suboptimal satisfactory driving experience.
If you’re not confident under the hood, it’s probably best left to a professional mechanic.

FAQs

While fuel injectors are individual, they’re designed to work together with the vehicle’s other injectors. If one fuel injector is faulty, replacing them all is recommended.
If your fuel injector is damaged or faulty, it should be replaced. Even still, cleaning fuel injectors at least once every 36 months or 45,000 miles is recommended. Replacing damaged or worn-out engine parts without improving performance isn’t ideal, but cleaning dirty injectors may improve engine performance. This process is relatively inexpensive, as you can buy fuel injector cleaner from most automotive stores to remove dirt and buildup from the injectors.
Several things can lead to a breakdown, but fuel contamination is the most common reason fuel injectors fail. Fuel contamination happens when debris in the fuel gets past the filtration, interfering with sealing surfaces.
