Why are fuel injectors so expensive?

Injectors have a tolerance of 1 micron, the finest tolerance of any mechanical component on the engine. To be able to manufacture at such precise standards and to afford the exacting quality checks along with it also helps to explain part of the costs of quality fuel injectors.

Are fuel injectors expensive?

While the price varies for every vehicle, the bad news is that in all cases, it's expensive. New fuel injectors range from several hundred dollars for basic vehicles up to over $1,000 for high-end vehicles and performance vehicles that require high fuel delivery rates.

What is the average cost to replace a fuel injector?

On average, you can expect to pay between $350 and $850 to replace your fuel injectors. The range of costs depends on a number of factors. Smaller vehicles with fewer cylinders requiring less expensive parts will come in at the lower end of the spectrum. Larger, high-performance engines will command a higher price tag.

Is it worth replacing fuel injectors?

But when you factor in the adverse conditions experienced in real-world driving coupled with a lack of proper maintenance, most fuel injectors might need to be replaced every 50,000 to 100,000 miles. If you still have some additional questions about the life expectancy of fuel injectors, don't worry.

How long are fuel injectors supposed to last?

With good, quality fuel injectors, you can expect them to last a long time. So, how long do fuel injectors last exactly? Some can be expected to last between 80,000 and 100,000 miles, while the best fuel injectors can last as long as you have your vehicle.

What is the most common cause of injector failure?

Common causes of injector failure

While many things can cause breakdowns, the most likely cause of premature failure is fuel contamination. Fuel contamination occurs when debris in the fuel gets past the filtration, destroying the sealing surfaces.

Should I clean or replace fuel injectors?

CARS.COM — Cleaning fuel injectors is a service frequently recommended by dealers and repair shops. But unless there are noticeable signs of clogged fuel injectors (such as a rough idle, stalling, poor acceleration or high emissions levels), it might not be necessary.

Is it OK to replace one fuel injector?

Unless you need to fix other things that may be causing your fuel injector to fail (which is usually the case), replacing only one will do little good and cost time and money. If the car is old and you have the budget, replacing all of them can help you avoid future problems.

What makes fuel injectors go bad?

Fuel injectors typically fail due to a buildup of contaminants such as carbon. Carbon build-up can cause a clogged or partially clogged injector, preventing the injector from closing all the way. This results in a drip that creates a misfire.

Can I replace my own fuel injectors?

Replacing a fuel injector seems like a daunting project, but with a little skill you can do the job yourself and save serious money. Shops charge a huge amount for fuel injection work. If you know that you have a bad injector, the job can be done at home.

What happens when injectors fail?

If a clogged fuel injector continually struggles to disperse fuel to the engine, a time will come when it misses the fuel supply completely and the engine will misfire. The misfire will easily be felt while driving, and often requires immediate repair by trained automotive repair specialists.

How many fuel injectors does a V8 have?

V6 or V8 engines will have a fuel rail with 3 or 4 injectors on each cylinder bank, while inline engines use a single rail that feeds all the injectors.

What happens if you don't code injectors?

Non start – In newer systems if you do not code in the injectors the vehicle will not start. Poor / lumpy running – as the injectors are not coded, the ECU will carry on fuelling as if the previous injector was still present, which can cause poor performance.

How can you tell if an injector is bad?

Can I drive with a bad fuel injector?

Technically, you can still drive with a bad fuel injector. However, it is advised against doing so because a failing fuel injector will cause the engine to run lean. This can lead to engine damage, poor fuel economy, and decreased performance.

What does a bad injector sound like?

You should hear a clicking sound as the injector is in use. If the injector lacks the clicking sound, it's dead and in need of replacement.

Will bad fuel injectors throw a code?

Diagnosing a Clogged Fuel Injector

One of the obvious symptoms of a clogged fuel injector is the lighting up of the "Check Engine" light in your dashboard. The fault codes usually associated with a clogged fuel injector can range from misfire codes to lean codes.

How long does it take to change fuel injectors?

In general, a fuel injector replacement should take 1 to 2 hours.

Will a bad fuel injector cause the check engine light to come on?

Do fuel injector cleaners actually work?

Yes! When used regularly, fuel system cleaners can help work to remove harmful deposits and keep new ones from forming. They are especially important for engines running on gasoline containing Ethanol and fuel-injected engines.

What will new fuel injectors do?

A fuel injector upgrade consists of replacing the stock injectors with a new set capable of delivering a higher flow rate. For example, think of a Ford Mustang with a 4.6-liter engine. The stock fuel injectors are good enough to deliver an adequate amount of fuel to the stock engine under any driving condition.

How many fuel injectors does a car have?

A car generally has one fuel injector per cylinder. So, if you drive a four-cylinder car, it will most likely have four fuel injectors.

Should I reset ECU after changing injectors?

You dont need to punch in a code or anything, but it would not hurt to reset your ecu after installing the new injectors to clear any check engine codes.
