NGK 52091 Spark Plug Wire Set RC-FDZ050 Blue Silicone 8mm Ferro Mag Core

The NGK 52091 spark plug wire set (also called ignition wires or plug wires, NGK series RC-FDZ050) is a replacement ignition cable set built to OE tolerances. It carries high-voltage current from the ignition coil or distributor to the spark plugs. It uses an 8mm ultra-low resistance magnetic core with a wire-wound design, which helps deliver a strong spark and suppress EMI/RFI noise.

Key Features:

• Ferro Mag core: stainless steel winding over a ferrite magnetic core gives ultra-low resistance and noise suppression.
• Blue silicone outer jacket: 8mm outside diameter, resists moisture, oil and cracking, and withstands underhood temperatures above 250°C (482°F).
• Reinforced insulation: high-density fiberglass braiding over EPDM/silicone inner insulation provides dielectric strength and cable tensile strength.
• Stainless steel terminals: serrated crimps grip the cable jacket and inner insulation for strong terminal retention and a secure connection under vibration.
• Silicone boots: OE-or-better spark plug and coil/distributor boots are sealed to the cable with silicone for a watertight fit. The spark plug boots are black, and a locking spring clip holds the plug terminal in place.
• Easy installation: cylinder lead identification tags, where possible, make correct routing simple.
• Warranty: limited lifetime warranty.

NGK is an OE ignition specialist, and these wires are made to match OE fit, performance and durability for dependable ignition performance.
