The unsightly stock valley cover with knock sensor provisions is often the first thing folks throw away. Because most folks turn off knock sensors when modifying their Gen 3 LS engines due to detecting false knock and other tuning inaccuracies. We made this knock sensor removal plate.
CNC Machined from a block of 6061 Aluminum, this cover accomplishes the above goal and looks good doing it.
A good way to verify your engine is a Gen 3 engine. Locate the factory cover and look for the "V shape" cutout in the back, or make sure your engine comes equipped with a rear camshaft sensor as opposed to one in the front timing cover.
Gen 3 engines were typically used from 97-04 in 4.8, 5.3 ,5.7 and 6.0 engines LS version engines.
