Good news about 1G knock sensors

It turns out that GP Sorensen, maker of aftermarke OE replacement switches, sensors, caps, rotors, modules, etc., buys factory OE Mitsubishi 1G knock sensors and simply reboxes them for sale to parts retailers.

I don't know about the 2G sensors, but I bought a "GP Sorensen" knock sensor from Advance Auto Parts because it was only $50 ($40 with my discount), and this is EXACTLY what I got, complete with Mitsu tag and white cap over harness.

Needless to say this was a pleasant and welcome surprise and may be of use to anyone looking to replace their factory knock sensor. It's possible the 2G sensor is the same way. Maybe someone will benefit from this information.

BTW, the part number for the 1G sensor is KS28 and I believe the p.n. for the 2G sensor was KS 32 (I think).
