Common Issues This Part Can Help Address

• Misfire caused by worn or damaged spark plug wires
• Rough idle from inconsistent spark delivery
• Ignition noise that can interfere with electrical systems
• Hard starting related to degraded wire insulation or core wear
• Loss of engine performance from weak secondary ignition transfer

Installation Notes and Tips

Verify the wire routing and terminal locations before removal so each lead returns to the correct cylinder or ignition connection. On 1995-1999 Toyota Paseo and 1995-1999 Toyota Tercel models, confirm the specific-fit configuration noted for the application, since the set includes plug leads and the remaining ignition points are direct ignition. Inspect related ignition components for wear before installation to avoid repeat service.
