Looks good never had to use.
It works great.
After replacing a bad knock sensor with this one my car started accelerating much easier.
My QX$ blew an engine before I had the chance to use it.
Work very good .
Wiring did not fit knock sensor.
Bought to go with Knock sensor but did not fit.
Packaged with another part it was supposed to fit (knock sensor).
Ordered new knock sensor and followed recommendation to order a new harness that is compatible with sensor, IT IS NOT and there is no return on the harness!!!!!
