Xspurt Fuel Injectors

Try them once and you will find it hard to use any other high flowing fuel injectors

Why You Will Love Them

These injectors are the latest in technology when it comes to performance fuel injectors. They start their life as a Bosch injector, some modifications are performed and adjustments to the flow rate are made and they emerge as Xspurt Injectors.

The real beauty of these injectors is that they have a very fine atomisation, especially at low revs. This means that even with 1170cc injectors you will get an idle that is pretty much the same as the factory set up. If you are a tuner, you will get this very smooth and consistent idle very easily and it will save you a lot of time trying to find the balance between idle and top end.

Some more reasons why they stand out as the best injectors on the market today:

You will get a smooth consistent idle very quickly with around 15:1 air/fuel ratio
Partial throttle tuning is also easy and smooth
Excellent control at low revs
No lean misfires
EXCELLENT atomisation – at low revs & the top end
Consistent flow rates with each set
High ohms means you won’t need a resistor box or inline resistor
They work very well at higher pressures, all the way up to 8 bar!

Troubles Tuning High Flow, Low Impedance Injectors

Have you ever tuned a car using bigger injectors (normally low impedance) and found that the car:

Is hard to start
Has a rough idle
Is rough at low throttle

Most of these problems will be because of lean misfire at idle and low revs due to:

Bigger fuel injectors have traditionally had poor atomisation
Inconsistency in fuel injected per cylinder and
Increase injector ‘dead times’ due to low resistance injectors needing a peak and hold driver to run them

Sizes and Fitments

They come in seven different flow rates:

We have adaptors for them to fit pretty much all top feed applications. We will supply alloy CNC extensions where needed to ensure the injector is the correct length. We can also supply the electrical connector to ensure they fit your wiring harness.
