Electronic Fuel Injection (EFI) is an important component of modern cars. It is responsible for injecting fuel into the engine at the correct time. It provides much more precise control and timing than carburettor type systems.

Electronic Fuel Injection has many advantages. Among them are:

Fuel economy
Better engine performance
Higher reliability
Lower exhaust emissions
Improved idle control

Properly serviced and tuned EFI engines can save up to 15% on your petrol costs.

Our workshop is professionally equipped for EFI diagnostics. That includes oscilloscopes, scanners, gas analysers and other tools and devices.

EFI comes in several varieties: "Throttle Body Injection" (TBI), "Multi Port Fuel Injection" (MFI) or Sequential Fuel Injection (SFI).

Electronic fuel injection is considered to be superior to carburetion because it allows more precise fuel metering for easier starting, lower emissions, better fuel economy and performance.
