Review on ACDelco Professional 213-4761 Engine Crankshaft Position Sensor: Performance at its Finest by Craig Lovro

As noted by another reviewer, the photo is inaccurate. Gaskets are not included and can be purchased from GM dealers or online. This is a great example of the differences between the Professional and Advantage part lines or part classes. 2005 4.3 that I know personally. I've seen both, the Advantage class is lighter and the sensor is all plastic (I think it was with period seals) Same lifespan? Time will tell good and accurate data. All GM dealers use the Professional version as a GM replacement part.
