When shopping for replacement fuel injectors, one thing you really want to be sure about is injector flow rate. A fuel injector's flow rate is a measure of how much fuel it can spray into a combustion chamber, and it's vehicle and engine specific.

When the injector fuel flow rate is correct, we have OEM-spec performance - your engine makes the power it's supposed to make, gets the fuel economy it's supposed to get, etc. And when the injector flow rate is wrong? All sorts of things can go wrong, from poor fuel economy to pre-detonation and engine damage.

Suffice to say, fuel injector flow rate is pretty darn important.

It's the last thing you want. You put your jet ski in the water or roll out your ATV and it wont' start. Or it runs poorly, sputtering and dying. Just like that your day is shot. You find something else to do, or spend the day tinkering with it, hoping to get it running.

Too often these problems stem from deferring maintenance, lack of use, or old fuel. These issues lead to clogged up fuel systems and dirty fuel injectors, the most common reasons why your vehicle runs poorly or lacks power.

Fuel injectors tend to last a long time, but several factors can clog them up and shorten their lifespan. Dirty injectors can also damage your engine if left for too long. That’s why getting them fixed should be a top priority.

Faulty fuel injectors can cause havoc with your car. Fixing or replacing them will help prevent serious engine damage and improve your car’s performance.

TLF Performance Parts has decades of experience in testing, cleaning, and remanufacturing injectors. Read on to see how to identify faulty injectors and what to do next.

For more power, you need more fuel. More fuel needs more air. Larger turbos, free-flow exhausts and upgraded intakes all work better with high-flow injectors.

Fuel injectors spray carefully calculated amounts of fuel into your engine. The best quality fuel injectors can last up to 100,000-miles, or even longer. On the other hand, some OEM makes may fail before your car hits 50,000 miles.

Why such a huge discrepancy between these figures? Simply because not all fuel injectors are created equal

Removing your fuel injectors may seem like a daunting task. But with a bit of guidance, you can do it yourself and save on labor costs. TLF Performance Parts even offers an expert advice service if you need some pointers before beginning - you can schedule a call here. Most fuel injection systems have a very similar layout, so these pointers will apply to a broad range of vehicles.

If you're shopping for replacement fuel injectors, you've probably noticed that there are two types of impedance ratings - high-impedance and low-impedance. The fuel injector's impedance relates to the electric current used - i.e. the amperage and resistance used by the injector to deliver fuel to the combustion chambers.

Most OEM engines use high-impedance fuel injectors, but it's important to know the difference. Using the wrong kind of fuel injectors will lead to performance issues and could cause problems with your vehicle's ECU and other engine management electronics.

With that in mind, let's look at the differences in fuel injector impedance and its application.

Your fuel injectors are a crucial part of your fuel system. They spray fuel into the cylinders or intake manifold of the engine and can cause issues if they are faulty. Injectors have the finest tolerances of any mechanical part in the engine and should be serviced every 24,000 miles. If you suspect that your injectors are malfunctioning and/or beginning to fail, there are several methods you can use to test them.

Fuel injector cleaning is the removal of contaminants and deposits in the injectors. Fuel injector nozzles have very fine tolerances that are required to properly atomize fuel for combustion. Particles or hard deposits can build up in the injectors over time for a variety of reasons. The build-up of these deposits will degrade the spray pattern of the injectors and affect performance and fuel mileage. If you're seeing a down turn in the performance of your engine, you might be wondering about fuel injector cleaning and what it can do to help your engine. This article will answer your questions about what to expect from the fuel injector cleaning process.

Upgrading to bigger fuel injectors is a great way to give your engine more power. Most engines are fuel injected nowadays. So it's become a popular way for car enthusiasts to increase horsepower without having to do more extensive mods. And, if more extensive performance upgrades are going to be done, larger injectors will help you get the most out of them.

If you're considering making this upgrade to your engine, you may be wondering if you should tune your engine. The answer is it depends on your vehicle. You most likely would need to tune your engine, but it's not necessary in all vehicles. Read on to find out why.

Upgrading your fuel injectors is one important part of increasing your engine horsepower. However, it's not the only thing you need to do to make your vehicle more powerful. Read on to find out how upgraded fuel injectors increase horsepower.

One of the most common questions we get is, "Will new fuel injectors improve my car's performance?"

The answer is both yes and no.

Yes, it's true that replacing old, worn fuel injectors is an easy way to improve an engine's efficiency. If you have an older vehicle with a set of worn fuel injectors, replacing them will help your engine run like new. You may even notice that your vehicle accelerates better.

But replacing an old worn out part with a new working part is not the same as adding horsepower. If you replace a fully functional injector with a larger injector - and make no other changes - that usually won't make your engine more powerful. Increased fuel flow is important, but it's only one part of making your engine more powerful.
