NGK 8129 RC-TE42 Spark Plug Wire Set Blue Silicone Ignition Wires

The NGK 8129 (RC-TE42) spark plug wire set, also called an ignition wire set or plug wire set, carries high-voltage current from the ignition coil or distributor to the spark plugs. It is built to OE tolerances and uses a blue silicone outer jacket. NGK is known as The Ignition Specialist, and its ignition parts are made to meet OE standards for durability and performance.

Key Features:

• Variable pitch winding: Wire wound over a magnetic core gives low resistance, a strong spark and good EMI/RFI noise suppression.
• High-temperature silicone jacket: Rated for 250°+ C (482°+ F). It resists moisture, oil and fuel, and cracking from temperature extremes.
• Stainless steel terminals: Positive-locking, corrosion-resistant ends hold tight and resist vibration and separation.
• Custom-fit boots: Spark plug and distributor boots meet OEM or better specifications, with a silicone seal at the plug boot.
• Easy installation: Wires are numbered for cylinder identification, and the coil wire is color coded.
• Insulation outside diameter: 5.00 mm.
• Warranty: Limited lifetime. See the package for details.

Replacing worn or cracked plug wires can help correct misfires, rough idle and hesitation. A fresh set also restores consistent ignition performance.
