Overview

RLP's Universal Spark Plug Wire Set is engineered to upgrade an OE ignition system for stronger, more reliable spark delivery in street-driven setups. The 8.5mm conductors are wrapped in a bright red silicone jacket that maintains a polished look while withstanding heat and moisture.

Durable construction you can feel

Inside, a tightly woven fiberglass braid forms the exterior, paired with a high-dielectric EPDM inner insulation to deliver stable electrical performance under varied temperatures. The stainless steel plug terminals resist corrosion and support long-lasting connectivity.

  • 450°F-rated silicone jacket protects the conductor from heat and splash, keeping the wires looking new.
  • Fiberglass braid adds strength to resist pulling and wear from engine movement.
  • RFI suppression helps minimize electrical noise for smoother idle and transmission shifts.
  • 5000 ohms per foot of resistance helps deliver ignition energy efficiently for a stronger spark (relative to lower-resistance options).

Fit, versatility, and daily use

Designed for universal and custom-fit applications across early and late-model vehicles, including HEI-equipped setups. This set replaces Accel 4041, offering a straightforward upgrade path for street performance enthusiasts. A two-year warranty provides reassurance if you ever need support.

  • All-weather reliability with a glossy appearance that remains presentable in daily drivers.
  • 90-degree boots minimize clearance issues when routing wires in compact engine bays.

Whether you're cruising the city streets or tackling weekend drives, the RLP spark plug wire set is designed as an upgrade option that aligns with your vehicle’s ignition system without guaranteeing specific results.
