Probably desirable, but not necessary. Many of the extenders do not make a good seal and will leak exhaust.

Have you read the install documentation? http://www.fuelsaver-mpg.com/doc/afr_efie_install.html

Where are you connecting to your o2 sensor, at the sensor under the hood, or somewhere else?

RE: wide band EFIE
You have to use the efie designed for the o2 sensor that comes with the vehicle, they are not interchangeable. There are some aftermarket WB sensors that have an adapter that can connect to an ecu that's designed for narrow band, but they are quite expensive and I don't know if they work any better for our application. AFAIK, only the Chrysler/Dodge/Jeep 5 wire o2 is compatible with both and the wb efie is the best choice for that. Other 5 wires o2's may also work with the wb efie, depending on what the 5th wire does.

Wide band is more accurate and able to control things better. Also, a wideband efie/wideband o2 combination is better able to control the mixture than the narrow band equivalent, apparently since the ecu trusts it more.
