just came from a web site 02 simulator.com. has anyone had any dealings with these things.the way i understand it that it is a computer chip that takes the place of the 02 sensor.were selling efies also but they were higher than hell!!!!
I dont know if anyone is interestead i have took what used to be called nonfoulers that used to screw on the 18mm sparkplug and drilled the center out then the o2 sencer will screw into the nonfouler thus it is now an o2 exstender
