Installation and Operation

Replacing spark plug wires requires caution and precision. Before starting work, disconnect the battery to prevent accidental engine startup. Pay attention to the insulation condition, as old wires often crack, leading to power loss or starting difficulties. When installing the new SIERRA set, ensure the cables are neatly routed and do not touch hot engine components or moving parts. Regular inspection of the wires prevents breakdowns during your cruise.
