What It Helps Address

  • Misfires caused by worn or heat-damaged ignition wires
  • Hard starting related to weak spark delivery
  • Rough idle from deteriorated wire insulation or terminals
  • Voltage leakage from cracked or aged plug wires
  • Poor engine performance from inconsistent ignition transfer

Installation Notes and Tips

Verify engine application before installation and route each wire to match the original layout. The 115-degree spark plug boot angle and 8mm insulation are important fitment details for Mustang ignition service, especially where clearance around the engine is limited. Confirm the distributor/coil end and spark plug end terminal types match the vehicle before final installation.
