This is a limited time offer. Get 2 of our famous Dual EFIE Deluxe for a reduced price.
This promotion was designed to help people who must treat downstream oxygen sensors. We have found that many more manufacturers are using downstream sensor information in their air/fuel calculations than was previously believed. However, you don't need to be using these on the same car. Take advantage of this promotion to get as many EFIEs as you like.
Each Dual EFIE Deluxe comes with:
- External voltage adjustment screws, so you can adjust the amount each EFIE circuit modifies it's oxygen sensor's output.
- Two ports for each EFIE circuit that accept multi-meter test leads, and hold them snugly so you can read the adjustments you're making without having to hold the leads (or open the box).
- An on/off switch.
- An enclosure with mounting flanges, to secure the EFIE to your vehicle.
- Five feet of cable.
