Why Choose an EFI system

There are enormous benefits associated with switching from an engine with carburettors to an EFI-equipped model, as the latter delivers a lot more power and torque. You will also enjoy greater fuel efficiencies, which will reduce your expenses and the wear and tear on your injectors, pump, fuel filters, and other vital components. The sensors and computer in your EFI system will optimise your air/flow ratio and ignition timing. They will automatically compensate for a range of factors to deliver superior performance.

EFI system engine swaps also give you better reliability and efficiency as you won’t experience problems caused by below-par air/flow ratios. Choosing one of our aftermarket EFI kits will also minimise time spent tinkering with your vehicle. While carburettors need constant adjustments, an EFI system will manage this on the fly for you. Eliminating the carburettor also means one less component needing to be serviced, maintained, and replaced over time.

Say goodbye to the difficulty of starting your vehicle on extremely hot or cold days — these aftermarket fuel injection systems will make the proper adjustments for easy starting. We stock the latest technologies and innovations in aftermarket electronic fuel injection systems that will deliver all these benefits and more.

Parts and Accessories for the Best Results

To get the most out of your performance EFI system, you need the right parts for the job. We have a full range of aftermarket options that have been specifically designed for performance, including:

• Fuel pressure regulators: Using your fuel pressure regulators in tandem with your EFI system, you can achieve power boosts in your vehicle and more extraordinary engine performance.
• Flow control valves: Oxygen is just as crucial for your performance as fuel. These aftermarket valves will ensure you are getting the correct airflow in your engine block.
• Fuel rails and accessories: To get the right volume of pressurised petrol to your injectors, you need quality fuel rails and accessories. We have the best aftermarket options on the market.
• Fuel tanks: You will get the most durable options in our range, designed to be anti-corrosive and rustproof, and built to minimise the risk of future leaks.

Whatever your car needs are, our team is here to assist. We are proud to stock the best aftermarket EFI kits Australia has to offer, and have genuine enthusiasts on deck to provide around-the-clock support.

Frequently Asked Questions

What is an EFI system?

An EFI system (Electronic Fuel Injection) replaces the mechanical fueling of a carburetor with an electronically controlled setup. It uses an EFI fuel management system (the ECU) to calculate the precise amount of fuel needed based on real-time engine data. Whether you are looking for self-tuning EFI kits that "learn" as you drive or a high-end performance EFI system for racing, the goal is optimal combustion and efficiency.

What sensors are needed for an EFI setup?

To function correctly, electronic fuel injection systems require several "eyes and ears" to monitor the engine:

• O2 Sensor (Oxygen): Mounted in the exhaust to monitor the air/fuel ratio.
• Coolant Temp Sensor (CTS): Tells the ECU if the engine is cold or at operating temperature.
• Throttle Position Sensor (TPS): Measures how far you’ve pressed the pedal.
• MAP Sensor (Manifold Absolute Pressure): Monitors engine load.
• Tach Signal: Tells the ECU the engine's RPM.

Can I use my existing throttle body with an aftermarket EFI system?

It depends on the type of EFI conversion kit you choose. If you are using a "Throttle Body Injection" (TBI) style aftermarket fuel injection system, the kit actually comes with its own throttle body that houses the injectors. If you opt for a multi-point EFI system for engine swaps, you may be able to adapt an existing throttle body, but most aftermarket EFI kits are designed as a matched set to ensure the sensors and linkages work perfectly together.

What parts do I need for an EFI conversion?

A complete EFI conversion kit typically includes:

• The Throttle Body/Injectors: To deliver the fuel.
• ECU (The Brain): To process data and control the system.
• Fuel Pump & Lines: High-pressure fuel pumps are the preferred choice rather than low-pressure carb pumps.
• Wiring Harness: To connect all sensors to the ECU.
• O2 Bung: To be welded into your exhaust.

Do I need ignition upgrades when fitting EFI?

While many EFI kits can run with a standalone ignition, many enthusiasts choose to integrate them. Upgrading to an ECU-controlled ignition allows your EFI fuel management system to adjust timing on the fly, which significantly improves power and fuel economy. If you are already investing in an aftermarket EFI kit, matching it with a compatible ignition system is the best way to get the most out of your performance EFI system.
