Manufactured using durable, high-conductivity materials with robust insulation and terminals, these cables are designed to withstand engine bay heat, vibration, and long-term use while maintaining optimal electrical performance.
A direct replacement set, these ignition coil ground straps are critical for maintaining ignition system reliability and preventing electrical faults.
Key Features
• Complete set of left and right ignition coil ground straps
• Suitable for Porsche 928S (from 1985 onwards)
• Provides secure grounding between ignition coils and cylinder head
• High-conductivity cable construction for reliable performance
• Durable insulation for engine bay conditions
• OEM-style fit and function
Function and Purpose
These ground straps provide the critical electrical grounding path for the ignition coils.
They help to:
• Ensure stable and consistent ignition performance
• Prevent electrical resistance or grounding faults
• Support proper spark generation
• Maintain reliable engine operation
Why Replace Your Ignition Coil Ground Straps
Over time, ground cables can degrade due to heat, corrosion, and vibration.
Common issues include:
• Corroded or oxidised terminals
• Frayed or damaged cables
• Increased electrical resistance
• Poor grounding leading to ignition issues
Replacing the ground straps restores proper electrical flow and helps prevent ignition system faults.
