NGK 51239 Spark Plug Wire Set, 6-Wire Blue Silicone

The NGK 51239 (RC-GMX017) is a 6-wire spark plug wire set engineered as a direct OE-quality replacement for select late-1980s through mid-1990s Chevrolet and Pontiac vehicles. NGK's ultra-low resistance magnetic core wire sets deliver a more powerful, consistent spark while effectively suppressing electromagnetic and radio frequency interference (EMI/RFI). The blue silicone outer jacket and inner EPDM/silicone insulation provide excellent dielectric strength and long-term resistance to heat, oil, and the demands of the engine bay.

Key Features:

• 6-wire set with 7mm insulation outside diameter and blue silicone insulation
• Stainless steel winding over premium ferrite magnetic core for ultra-low resistance and superior EMI/RFI noise suppression
• High-temperature premium silicone outer jacket with EPDM/silicone inner insulation for outstanding dielectric strength
• Spark plug boots (6 straight, 180°) made from silicone and glued to cable with silicone sealer for a watertight seal
• 90° coil end boot in black; spark plug end boots in brown
• Stainless steel terminals with up to 3 serrated crimps for maximum terminal retention strength
• Locking C-shaped spring clip with corrosion-resistant plating for a secure, positive spark plug terminal connection
