NGK 9799 Spark Plug Wire Set, Magnetic Core, Blue Silicone, 7mm

The NGK 9799 spark plug wire set (also called an ignition wire set or spark plug cables, NGK series RC-TX99A / TX99A) is a direct-fit replacement ignition wire set. It carries high-voltage current from the ignition system to the spark plugs. NGK builds it to OE tolerances, with terminal boots designed for an exact fit instead of a universal one.

Key Features:

• Magnetic core, variable pitch winding: The loose/tight/loose winding suppresses radio frequency interference across a wide range.
• Blue silicone insulation: The outer jacket is rated for underhood temperatures above 250 °C. EPDM or silicone inner insulation gives strong dielectric strength.
• 7 mm outside diameter (about 0.275 in).
• Stainless steel terminals: They hold the connection securely for the life of the set.
• Cylinder lead identification: The wires are numbered for easy cylinder identification, which makes installation simpler.
• Limited lifetime warranty: See the packaging for details.

NGK has more than 80 years of ignition experience and is known for OE-quality ignition components. This wire set is a dependable choice when you need consistent spark delivery and reliable engine performance.
