Detailed Description

Walker ThunderCore PRO 924-1781 is a spark plug wire set engineered for direct ignition service on 2001-2005 Mazda Miata models.

What It Helps Fix

• Engine misfire caused by worn or damaged plug wires
• Hard starting related to weak ignition transfer
• Rough idle from deteriorated wire insulation or terminals
• Spark leakage from heat-aged boots and tips
• Intermittent ignition performance on Mazda Miata models

Installation Notes
