NGK Spark Plug Wire Set for 1990-1994 Lexus LS400 and SC400 (6403)
$322.96
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 1990-1994 Lexus LS400 and 1992-1994 Lexus SC400 Base models.
This premium NGK spark plug wire set (MPN 6403) is engineered to restore ignition efficiency and suppress electrical interference in your Lexus V8 engine. Utilizing a variable pitch magnetic core, these cables produce the precise impedance required to eliminate EMI/RFI noise across the entire frequency spectrum, protecting sensitive onboard electronics. The outer EPDM and silicone jackets provide superior dielectric strength and thermal resistance to withstand the high-voltage demands and harsh temperatures of the engine bay.
- Durable Construction: High-quality insulation ensures excellent voltage containment and long-term reliability.
- Watertight Seals: Spark plug boots are glued to the cable with a specialized silicone sealer to prevent moisture intrusion.
- Secure Connections: Stainless steel terminals feature up to three serrated crimps for maximum retention, while C-shaped spring clips with corrosion-resistant plating ensure a positive connection to the plug.
- Specifications: Variable pitch resistor technology; Limited Lifetime Warranty (see package for details).
