Hey, I have been wanting to put an air to fuel ratio gauge on my truck now but nobody at any of the autopart stores seems to have a clue how to do it and the work entitled. Does anybody know how to do this? It would be goin on an 04 F150 w/ a 5.4, thanks.

Get one from Summit Racing. My guess is you can find one that ties into your stock Oxygen sensors, but you can go first class and get one that comes with its own oxygen sensor and you can have a bung welded into the exhaust at a local exhaust shop.

All vehicles should come stock with a bunghole.

narrow band o2 gauge (the kind that hooks to the stock o2) - total waste of money

wide band is the only way to go. thats the kind that comes with its own o2 sensor

Dang, the wideband ones are expensive as hell, the ones I had seen at autozone were only like $50 but didn't include the O2 sensor. How much better are the widebands exactly?

narrow band is total garbage. they just dance around from rich to lean because thats what the stock o2 is designed to do. they run on a scale from 0-1v. a wide band runs from 0-5v making them stable and more accurate. with a narrow gauge you will never get a digital number, a wide band will give you an actual number to look at.

long story short, if you just want an extra gauge in the truck that looks cool, get the narrow band but keep in mind, it will provide you with absolutely no usable information. if you want a gauge that gives usable information, its wide band or nothing
