Why a QUAD? Because despite earlier reports that the downstream sensors don't matter, there have been increasing reports on the forums and in our experience that they do! SO if you have had trouble with your car getting the increase it should be getting, think about upgrading to a digital narrow band quad EFIE and treat those back O2 sensors for the same price as just 2 front ones in the old style efie's.The Quad Digital EFIE allows much leaner settings on vehicles than other older types of EFIE's which are analog. We are now recommending Digital EFIEs for all narrow band oxygen sensors that are upstream of the catalytic converter. (Note: The Quad EFIE uses a pair of analog EFIEs for the downstream sensors)
