For buyers searching for a Mercedes-Benz C320 spark plug wire set, Mercedes-Benz E320 ignition wire replacement, or Chrysler Crossfire ThunderCore PRO wire set, this part is built to match OE-style fit and electrical performance requirements. The Walker 924-1820 part number is useful when replacing aging ignition wires that no longer maintain consistent spark delivery.

What This Part Helps Address

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

Installation Notes

Verify engine application before installation, especially on Mercedes-Benz E320 models where fitment notes specify a 12-lead set for 1998-2002 vehicles and ThunderCore PRO coverage for 2003-2005 vehicles. Route each wire to match the original layout, seat the boots fully on the plugs and coil connections, and apply the included dielectric grease where appropriate to help with boot sealing and future service removal.
