Fuel Injection Conversion Kits

Bring reliable classic vehicles into the present day with a fuel injection kit or throttle body conversion kit from Eastwood. Electronic fuel injection, or EFI for short, has many advantages over traditional carburetors. Among other things, EFI systems are more efficient, produce better throttle response and require much less maintenance. If you drive a car with a carburetor but want to experience these benefits and others, an EFI kit is the way to go. These kits are designed by high-performance automotive leaders such as FiTech, Holley and MSD.

Upgrade to Fuel Injection Fast

These kits are designed for DIYers so they can convert to EFI quickly and at an affordable price. We carry the best small block Chevy fuel injection kits along with systems for classic Ford and Mopar engines — and even Jeep EFI kits. The Holley Sniper EFI Self-Tuning Master Kit is a highly recommended Chevy 350 fuel injection kit. Since no post-install tuning is required, it's great for beginners. Both two-barrel and four-barrel kits are available for engine that crank up to 800 horsepower.

An alternative to EFI is throttle body injection. This system involves a single fuel injector rather than one injector in each cylinder; it was developed in the early days of fuel injection as a cheaper and easier way to make the switch. Get a throttle body injection conversion kit if you want most of the EFI benefits in a design similar to a carburetor. For great looks to go with the power boost, get your kits painted in black, silver or gold.
