Hey Guys,

Im going to be doing the knock sensor replacement this weekend (thanks for the great info on this subject here). Ill be replacing the sensors and harness but was wondering if I need to use any silicone on the intake gasket during reassembly. This is on a 2000 5.3 silverado.

Thanks.

Thanks to the rest of you that now have me looking at, regearing, PCM tune, Long tube headders and so on .......
