anybody ever heard of an evo ix without a front o2 sensor or even the housing it?!

nevermind i found it!

the o2 housing bolts to the turbo and necks down where the downpipe attaches to it. it doesn't connect to the head, or the exhaust manifold. the o2 sensor sits in the o2 housing. it will be located under the exhaust manifold.

if the car isn't using the stock ecu, people remove the front o2 sensor sometimes because they don't need them. stock ecu needs the front o2 sensor or else it will idle like garbage and cruise AFR will be all over the place.
