Throttle Body Fuel Injection or “TBI” systems are available in several different configurations to suit your specific requirements and budget. This type of EFI system is available from a fully electronic spark control unit to a basic functional system.
If you are looking for the most economical way to replace your old carburetor, these systems are the ideal option. TBI systems provide great starts, drivability, and fuel economy at around half the price of MPFI units.
TBI systems available from Affordable Fuel Injection are easily installed. There is no need to replace the intake manifold with use of the AFI manufactured adapter plate. Simply remove the carburetor and install the adapter plate and TBI unit in its place. This along with a very simple hook up plus EFI items, and you are ready to operate.
