NGK 8146 RC-TX89 Spark Plug Wire Set, Silicone Magnetic Core Ignition Wires

The NGK 8146 (RC-TX89) spark plug wire set, also called an ignition wire set or spark plug cable set, is a direct-fit replacement for worn or deteriorated ignition wires. It carries high-voltage current from the ignition system to the spark plugs. Replacing old wires helps restore reliable ignition and smooth engine performance. NGK has been a leading OE ignition supplier for decades.

Key Features:

• Variable pitch magnetic core: Produces the impedance needed to suppress EMI/RFI interference across the frequency spectrum, and provides uniform resistance.
• Silicone outer jacket: The high-temperature silicone jacket resists underhood temperatures up to 250°C.
• Reinforced construction: Fiberglass-reinforced braiding over EPDM/silicone inner insulation gives strong dielectric properties and good tensile strength.
• Silicone insulation: Blue, 7 mm outside diameter.
• Boots and terminals: Black silicone boots with stainless steel terminals. A silicone seal at the spark plug boot helps keep out moisture and contaminants.
• Fit and finish: Specific-fit assembly with 180° spark plug boots and 90° distributor-end boots.
• Grade: Standard replacement, backed by a 1-year warranty.

Other part numbers for this set include TX89 and RC-TX89 (UPC 087295081464). Follow the NGK installation instructions and replace the wires one at a time to keep the firing order correct.
