NGK Part 4447 Spark Plug Wire Set for Toyota 4Runner and Tacoma – High-Performance Ignition Cables

NGK variable pitch resistor cables provide uniform resistance and ensure outstanding electrical conductivity in high-quality cables. Outer EPDM/silicone jacket and inner insulation contain high voltage currents for excellent dielectric strength. NGK variable pitch magnetic core cables produce the necessary impedance to suppress interference throughout the entire frequency spectrum for exceptional EMI/RFI noise suppression. OE or better specified spark plug and distributor boots ensure the highest quality fit, performance and durability in every application. Spark plug boots are glued to NGK cable with a silicone sealer for a watertight seal. Stainless steel terminals utilizing up to 3 serrated crimps bite into cable jacket and inner insulation for the highest terminal retention strength (wherever possible). Locking C-shaped spring clip with corrosion-resistant plating ensures a secure and positive spark plug terminal connection. 4 Wires (Coil Lead N/R)

• LIMITED LIFETIME WARRANTY: See package for details

The NGK Part 4447 spark plug wire set is specifically designed for Toyota models including the 1994-1997 Tacoma, 1995-1996 T100, and 1996 Toyota 4Runner, offering reliable ignition performance. These wires feature a variable pitch resistor design that ensures uniform resistance across all cables, which contributes to consistent spark delivery and optimal engine performance. The outer jacket is constructed from durable EPDM/silicone material, providing excellent weather resistance and high dielectric strength to contain high voltage currents securely. The internal insulation maintains integrity under demanding conditions, ensuring long-lasting performance and safety.
NGK's magnetic core technology produces the necessary impedance to effectively suppress electromagnetic interference (EMI) and radio frequency interference (RFI), reducing noise and preventing signal disruption in your vehicle’s electrical system. The cables are paired with OE or better specified spark plug and distributor boots that guarantee a precise fit, enhancing durability and performance. These boots are sealed with silicone sealer to ensure a watertight connection, preventing moisture ingress which could lead to misfires or performance loss.
Stainless steel terminals with up to three serrated crimps provide exceptional retention strength by biting into the cable jacket and insulation, ensuring a secure connection even under vibration. The locking C-shaped spring clips are plated for corrosion resistance, maintaining a positive and reliable connection over time. The set includes four wires, making it ideal for complete ignition system upgrades or replacements. Backed by a limited lifetime warranty, the NGK spark plug wire set is an excellent choice for drivers seeking high-quality, durable ignition cables that meet or exceed OEM standards. This product is not CARB approved but complies with Prop 65 requirements, ensuring safety and environmental standards are met.
Engineered for easy installation and long-term reliability, these ignition wires deliver consistent spark delivery, noise suppression, and resistance to harsh conditions, making them a trusted choice for your Toyota’s ignition system.
