Your EFIE Information
by: Hydrogen Water Cars

Hello Again Les,

Gettting back to you on information you requested for your o2 sensors. GMC 350


You have 1 narrow band sensor upstream of your catalytic converter so one of our single narrow band EFIE?s is what would work.

We usually still recommend the ?Quad Digital EFIE? in these cases because it has the superior digital circuitry and it?s the most flexible if ever used on another vehicle.
