What This Wire Set Helps Address

• Misfires caused by worn or damaged ignition wires
• Weak spark transfer from coil to spark plugs
• Radio-frequency interference in ignition systems
• Cracked, brittle, or heat-aged wire insulation
• Rough idle and inconsistent throttle response tied to ignition loss

Installation Notes and Tips

Verify engine and ignition configuration before ordering, since fitment varies by year, model, and whether the vehicle uses High Energy Ignition (HEI). Several applications are listed for vehicles without HEI, while others are specified for HEI-equipped models or for engines with plugs above the manifold. Route each lead to match the original layout and confirm secure terminal engagement at the distributor cap and spark plugs.
