The braided shielding needs to be continuous from the knock sensor to its connection at the DME as it acts as the ground. If it is not, the knock sensor will not work and the DME will retard timing.

It would be difficult to get heat shrink over the wire without disconnecting it from the harness. You can use conductive foil tape though. To do this properly you will need to remove the intake manifold.
