Instructions on ngk website state sensor must be installed 10x the dia of the collector from the end of the collector. 3 1/2 x 10=35". anybody else have a problem.

No, we do not have that problem, and we've run the AFX setup for a year and a half. Almost any O2 sensor system will have those same instructions. What it means is that on a race car, unless you have a system on the car after the collectors, you'll get lean readings at idle and low RPM. When it's going down the track, it'll read just fine. At idle, the O2 readings are useless.
