EFIE - $60
Electronic Fuel Injection Enhancer – required for any ER HyZor installation on a vehicle with a narrow-band oxygen sensor. It is a simple device that allows you to cut back the fuel flow to your engine allowing fuel savers such as the ER HyZor to work on today's computer controlled vehicles.
This is the original EFIE developed by George Wiseman.
Includes EFIE and installation manual.

Wide Band EFIE
Currently I do not sell
the wide-band EFIE. Please click the link below and place your order.
The FuelSaver-MPG site carries the original narrow-band EFIE along with the new wide-band EFIE (pictured at right).
The wide-band EFIE is needed for wide-band oxygen sensors and does not work on narrow-band oxygen sensors.
The availability of both narrow and wide-band EFIEs now allows many Fuel Savers to work on virtually any vehicle.
FuelSaver-MPG also has other EFIEs for sale.
