Looking for our Wideband Kit without the Gauge? Click Here.
Wideband logging to your ECU made simple! A wideband O2 sensor (air/fuel meter) is required for any tune and we've made the install as easy as plugging it in. No wiring diagrams, crimping, soldering, or splicing here!
This product is great for e-tunes or dyno tunes and customers who are searching for a gauge display in their interior while tuning.
To install, mount the AEM Wideband controller in the engine bay, run a couple wires into the cabin and just plug it in!
This product is compatible with the Cobb Flex Fuel Kit.
Gauge size is 52mm.
2004-2013 Forester XT

Please Note: We cannot sell the plug and play wiring separately from the unit. We need the wideband unit in house to modify it to make it easier to install.
