Product Details

The 7mm wire diameter supports a factory-style layout, while the silicone boot material helps maintain secure connection points at the spark plug end and distributor/coil end.

What It Helps Fix

• Misfires caused by worn or damaged ignition wires
• Hard starting related to weak spark delivery
• Rough idle from deteriorated wire insulation or boot connections
• Intermittent ignition performance on aging Volvo ignition systems
• Voltage leakage from cracked or heat-aged wire sets

Installation Notes

Verify wire routing against the original layout before removal, especially on Volvo 240, Volvo 760, and Volvo 940 engines with factory-style ignition routing. Match each lead to the correct spark plug and distributor or coil connection, and confirm the 180-degree spark plug boot orientation clears nearby components. Use the vehicle’s service information to confirm the exact application before installation.
