Hey guys , what would be the best place on the header to put an o2 sensor in for my a/f ratio monitor Thanks
The best place is in the collector or behind the crossover pipe. The wire will probably not be long enough for those so it won't make much difference which tube you put it in.
Mine is in the first section of pipe just after the collector, as close to the connection flange as I could get it. Are you gonna use a heated sensor?
