What EIFIE do i need
I have 2 trucks. One is a 1997 ford f-150 with a 4.6ltr engine and has two 02 sensors with 3 wires (2 white and 1 grey)

The other is a 2003 siverado 2500 with an 8.1ltr and has two 02 sensors with 4 wires.

Will the EFIE's work on these trucks and which EFIE model will I need ?

Any comments on the HHO expected fuel economy with on without the EFEI'S

I would think the Ford has o2 sensors, but you need to confirm the Chev. has o2's not air-fuel sensors.

If you have 2 o2 sensors before the cat (which most V8's will have), then the double EFIE is the way to go.
