Standard Motor Products 55914 8mm/7mm Silicone Spark Plug Wire Set

The Standard Motor Products 55914 is a vehicle-specific silicone spark plug wire set engineered as a direct OE replacement for properly routed, reliable ignition performance. Featuring a dual-diameter design with 8mm primary wires and 7mm distributor wire, this set delivers low-resistance signal transfer and strong suppression of radio frequency interference (RFI) to protect sensitive onboard electronics.

Key Features:

• Silicone insulation withstands extreme underhood heat, oil exposure, and ozone degradation for long service life
• 8mm and 7mm wire diameters provide a direct-fit, factory-style replacement with no modification required
• Low-resistance conductor ensures full spark energy reaches each plug for efficient combustion
• RFI suppression minimizes interference with radio, sensors, and engine management systems
• OE-matched boots and terminals snap securely onto spark plugs and distributor or coil for a rattle-free, moisture-resistant connection
• Vehicle-specific design for correct routing and proper fit without trimming or splicing

Standard Motor Products has been a trusted name in ignition components for decades, manufacturing parts to OE specifications. The 55914 wire set is an ideal choice for a tune-up or ignition system restoration, helping to eliminate misfires, rough idle, and hard starting caused by deteriorated spark plug wires.
