If you’re tired of messing with jets and needles, replacing your carburetor with a Fuel Injection System has never been easier. If you make the right choices, the system will work great with engine you have today. It can also support your planned upgrades.

Horsepower Rating
EFI kits are sized by the maximum horsepower they can support with gasoline. They will work across a wide horsepower range.

Injection Style
Throttle body injection offers the easiest installation and Wiring. It can also work with your existing intake manifold and air filter. Multi-port injection gives you the most accurate fuel delivery, but at a higher cost.

Tuning Options
Most kits are self-tuning, but they also have powerful user-tuning tools. You can even have different settings for the track and the street.

Metering Style
Most kits are Alpha-N, Speed Density, or a combination of the two. Alpha-N is the simplest and requires tuning to be done manually. Speed Density uses more sensors and allows the system to self-tune.

Ignition Timing Control
Many EFI kits are capable of timing control when used with the right ignition system. If this is something you want to do now or later, you’ll need a compatible kit from the start.

Power Adders and/or E85
Many EFI kits work with nitrous, boost and/or E85. If you want to use any of these now or in the future, it is best to buy a compatible kit from the beginning.
