easy! but you need to weld a bung into your exhuast for a O2 sensor. If you have MIL's I don't think you can tap into your existing ones, not sure though.

the mils effect the rear o2's only. you can get signal for the gauge from a pin at the computer although i'm not sure what number it is. with that being said, the typical a/f gauge from autometer is nothing more than a light show. unless you just want some pretty lights bouncing around dont bother.

right now he really doesnt need either.the autometer one is useless and the price of the widebands being what they are, it would be a waste of money for him right now.

For the $450-500 it would cost for a wideband O2 gauge, you could get on a dyno many many times. If you plan to do a lot of tuning on your own car, then it might be worth it. Ask yourself how many times do you expect to adjust your a/f ratio, then do the math.

very easy install... you can either go to the PCM or do what i did and run it through the firewall under the car and tap right into the o2 sensor... on my 04 it was the black one

this may seem like a dumb question but can u just get a a/f gauge and tap an other o2 farther down the exhuast. and i think if that would work it would be cheaper then getten the real deal.

You can get a wideband for as low as $300. But there are really only two reasons to have one. Self-tuning and a safeguard if you are running a power adder.
