Product Details

The Walker ThunderCore PRO line focuses on ignition wire construction that matches OE expectations for fit, materials, and performance. Part number 924-1221 uses high-temperature silicone components, stainless steel terminals, and protective tubes to help maintain stable spark delivery under demanding underhood conditions. This spark plug wire set is a practical choice for drivers servicing a Chrysler Cirrus, Dodge Neon, or Mitsubishi Eclipse where accurate ignition routing and durable insulation matter.

This part cross-references DENSO Auto Parts (e.g., 671-4072) for the same application.

What It Helps Address

• Misfires caused by worn or heat-damaged plug wires
• Hard starting related to weak spark transfer
• Rough idle from inconsistent ignition output
• Voltage leakage from cracked boots or deteriorated insulation
• Intermittent engine performance issues on aging ignition systems

Installation Notes

Route each wire to match the original layout and keep the leads separated to reduce crossfire. Inspect spark plugs, coil connections, and wire retainers before installation, and apply the included dielectric grease where appropriate to help seal boots and ease future service. Verify fitment by year, make, and model before ordering.
