How do I know if a fuel injector replacement is required?
If a fuel injector replacement is required during repairs, refer to the Electronic Parts Catalog to verify that the correct injector is ordered and installed. Here’s how to identify and order the correct injector.
How do you open the injectors on a GTI MKV?
You are going to be opening holes that go into the engine so before you begin get a can of compressed air and blow all the dust and debris away from the injector ports. You will need to remove the intake manifold on the GTI MkV to get to the injectors.
What causes multiple fuel injectors to go bad?
This issue could be caused by a failing ECU, or one of the injectors along the fuel rail may be faulty. The electrical pulse is transmitted through each of the injectors to one another, so one faulty injector could cause issues in multiple injectors.
Where is the fuel injector on a V10 engine?
The fuel rail is a cylindrical rail that will run along the top of the intake manifold, and each fuel injector will be between the fuel rail and the intake manifold. V style engines (V6, V8, V10) will have two fuel rails with half of the injectors on each side of the motor. Find a long metal rod or screwdriver.
Do I need a tune if I upgrade fuel injectors?
Fuel injectors directly affect the air/fuel ratio for the engine and new fuel injectors do require a new or updated tune.
How do I know if I need bigger injectors?

Do bigger fuel injectors do anything?
The larger the diameter, the more fuel an injector can deliver. As fuel injector size increases, there are some unwanted side effects. As an injector's hole gets bigger, the minimum amount of fuel it can flow also gets larger.
How do I know what fuel injectors I need?
Fuel Injectors are sized by their flow rate. Flow rate is a measurement of how much fuel can be delivered over time. It is listed in pounds per hour (lbs./hr.) or cubic centimeters per minute (cc/min.). The right size injector can supply enough fuel under full load conditions at an 80% duty cycle.
Do bigger injectors add horsepower?
3. Larger throttle body and injectors. A larger high-performance throttle body will deliver more horsepower. Depending on what type of engine you have, you can gain as much as 10-20 more horsepower and comparable torque.
Are bigger injectors worth it?

That's it for tech Tuesday.
Can I put bigger injectors on stock engine?
You can;t do a stock tune unless you can fool the ecu into thinking it is getting more or less air. If you throw in bigger injectors it will hold that injector open for the same amount of time as the smaller injectors and it will dump TONS of fuel in.
Will new fuel injectors make a difference?
A new or upgraded fuel injector can improve engine performance, reduce diesel emissions, and increase the uptime of your truck. Don't wait for a better system to come on the market, though, because when it's worn out, part of the fuel injector – or even the entire system – should be replaced.
Will bigger injectors hurt mpg?
In the end, do not upgrade to larger injectors in an attempt to get better fuel mileage, as new stock sized injectors will do the job if your current injectors are worn out. But at the same time, if you are looking for more power, do not be afraid to go to a larger injector because of losing fuel economy.
What brand of fuel injectors are best?
The Top 9 Fuel Injector in the Global Market:Denso Fuel Injector.Delphi Fuel Injector.Magneti Marelli Fuel Injector.Edelbrock Fuel Injector.Keihin Fuel Injector.Woodward Fuel Injector.Continental Fuel Injector.Stanadyne Fuel injector.More items...•
What is the difference between EV6 and EV14 injectors?
The EV6 injector is nearly identical in height but the body of the fuel injector is narrower or “skinnier” when compared to the EV1 injector. The third style is the EV14 fuel injector. The EV14 injector is shorter than the EV1 and EV6 injectors and features a slim style body.
Are all fuel injectors the same?
There are two distinct types of fuel injectors: high impedance units, and low impedance units. A high-impedance injector (aka saturated) uses a high resistance value of around 12 ohms across its coil, but runs at low current levels to keep the circuitry cool.
Why are Bosch injectors less popular?
These units are becoming less popular now mainly because they don’t deliver the high flow rates now demanded by today’s more powerful engines. These Bosch injectors used a connector that is referred to by no less than three different aliases.
What injectors are used in 2005 LS3?
Perhaps a bit earlier, around 2005, GM switched the passenger car injector style to the Gen IV, short LS3 style that uses the EV6 or USCAR connector. This is the shortest injector of all the factory squirters, but its size should not be confused with a lack of flow potential as these injectors can crank out the fuel.
What is the name of the Bosch fuel injection system?
The earliest reference is the Jetronic –the Bosch name for its early fuel injection system. This connector evolved into the Minitimer that now morphed to EV1. Right away, this becomes mystifying with three different ways to describe this electrical connector.
Why don't fuel rails work on different engines?
It should also be noted that Aeromotive warned us that they don’t recommend adapting fuel rails to different engines because of the potential for a high pressure fuel leak between the fuel injector and the rail. This warning would likely also extend to use of adapters.
Does GM carry injectors on trucks?
Unfortunately, GM didn’t carry this injector over to the trucks, choosing instead to go with an entirely different injector.
Do truck injectors need an adapter?
Since most aftermarket EFI systems target the more modern EV6 injectors, using the early truck injectors will often require an electrical adapter. (Left) This is the original Bosch Jetronic injector with its EV1 connector that is also called the Minitimer.
Can you kill a stock engine?
That said, as with all engines, you can easily kill a stock or lightly modified engine with a lack of mechanical sympathy and maintenance.
Does BHP kill engines?
BHP doesn't kill engines. RPM and torque, more so torque, does. High torque and lower RPM causes massive cylinder pressures and can bend rods (more likely) and crack piston rings and their landings (less likely).
How to find fuel injectors?
Open the hood and locate your fuel injectors. The easiest way to locate the fuel injectors for your specific vehicle is to refer to the service manual for that vehicle. Most applications have one fuel injector for each cylinder.
Where is the fuel rail on a V8?
The fuel rail is a cylindrical rail that will run along the top of the intake manifold, and each fuel injector will be between the fuel rail and the intake manifold. V style engines (V6, V8, V10) will have two fuel rails with half of the injectors on each side of the motor.
How to test if a car has electrical system?
1. Turn the key to the “on” position without starting the engine. To conduct this test, the vehicle's electrical system must be active without the engine actually running. Insert the key and turn it until the electrical system activates, but stop before you engage the engine's starter.
Can fuel injectors fail?
There are a number of issues that could cause your fuel injectors to fail. Although some may be beyond the expertise of most home mechanics, you can often diagnose a faulty fuel injector using common hand tools. Steps.
Why is there a cut out in the head of my injector?
Note the angle of the new injector. There is a cut out in the head to clear the wiring connection, make sure you take note of that when installing the injector. The injector will not seat correctly if the cut out for the harness connection is not lined up.
What does a direct port injector do?
On a direct port injection motor a properly working injector will send a precise amount of atomized fuel into the combustion chamber at a designated time . A weak or improperly working injector can do everything from send no fuel, to leak raw, non-atomized fuel into your engine. If you are going to be replacing your injectors, ...
Do injectors come out with a manifold?
When removing the manifold some times the injectors will come out with the manifold (red arrows). This is not uncommon but most of the time the injector seals to the fuel rail are the weakest point and the injectors will stay in the engine. Remove the manifold carefully in case some injectors stay in the head and some come out with the manifold.
Can the intake valve interfere with the nylon brush?
Note: the intake valve may interfere with the Nylon brush necessitating turning the valve train for clearance. If you have not disconnected the timing belt you will be fine but if you have removed the belt and turn the motor or valve train make sure to line everything back up again.
