LS INTAKE MANIFOLD MODS Good and Bad

A little video about common Ls intake manifold modifications and why I personally do or dont condone them and why. Demonstrated while installing my LS6 intake manifold.
GM TSB #02-06-04-023 addresses the silicon dam around the rear knock sensor to prevent corrosion prominent in vehicles where consumers used high pressure water to wash the engine bays.
Again an example of having to create a secondary solution to a problem that common sense would have prevented. 🤦‍♂️
