Was about to buy the Defi D-Series gauges when i realized that the AFR gauge doesn't come with an air fuel sensor???confused...please advise me

....forget the AF gauge for your car...unless you spend ~$350 and get a true wideband setup, with datalogging capability.

The stock sensor is not going to work.....it will be an expensive, useless gauge.

....also....before you post any more useless threads, search....or at least READ the top page of the forum to see if it isn't alerady under current discussion....

A/f guages are met to be used with oem o2 sensors. In the case of the wrx, the rear o2 sensor is used.

Uncle Scotty is correct however, you can not use an a/f guage to tune with, for that you need a wide band.

....sorry d00d....it is useless....100% useless with the stock sensor.....just pure bling...expensive, useless, potentially big issue causing, bling.

Uncle Scotty you type to dam*ed fast.

A lot of people want them even if they are useless, because they are into the bling and not the performance aspect.
