Mechanic said these were bad. Both were bad.

The gasket brackets are about 2 mm to long for an 04 Silverado 2500hd meaning I had to hold them in place while I reinstalled the intake manifold. Gaskets were tight though. The knock sensors and cable im not sure even work. After installing everything my check engine light still came on with the same code only this time both weren’t working. Fuel mileage dropped drastically and didnt seem to have much power. So I uninstalled these and just went to autozone.

Purchased for a 2002 GMC Sierra 5.3. The intake gasket clips were incorrect and the silicone gaskets inside of the plastic had holes in them and would leak. The knock sensors seem ok but gasket was definitely wrong

The first set of sensors were defective and came out without any problems. The second were defective as well and when I tried to remove them they would not come out. Had to drill a pilot hole and install a screw in the sensor on one side to keep the sensor from spinning at the top of the crimped area. By doing that it allowed the sensor to turn so it could be removed. Not the best quality. Order delphi when replacing the knock sensors. It is cheaper in the long run. I had to do this a total of 3 times. P.S. The company is great, just the sensors are not so.
