Verify wire routing against the original layout before removal to avoid crossfire or interference with hot or moving components. Confirm the 90-degree spark plug boot orientation and terminal types match the vehicle’s ignition layout before installation. For best results, inspect related ignition components such as spark plugs, distributor cap, and coil connections during service.
