Well, went to install my o2 housing saturday and guess what? In a real fit of genius mitsu cross threaded o2 sensor into the stock housing. I was so ticked off I sold my megan o2 housing on the spot to another evo own
At this point, I'm not spending $190 to replace a sensor for a $120 mod. If the stupid thing ever goes bad, I'll think about it then.
In the mean time, I'll just pick up a LICP
