Mercury – Quicksilver 816608Q70 Red Wire Spark Plug Wire Kit | GM V8 Marine Engines | Delco HEI Ignition | 816608Q70 Overview A strong, even spark keeps your boat running smooth and powerful — and that starts with quality plug wires. The Quicksilver 816608Q70 Red Wire Spark Plug Wire Kit is made for V8 GM-based marine engines (305 and 350 CID) running Delco HEI ignition systems between 1995 and 1998 . Each wire is built for precision, cut to the exact length for your setup, and finished in a durable red jacket that’s made to handle marine heat, vibration, and moisture. It’s a simple upgrade that restores the crisp ignition response and dependability your engine was designed for. Key Features Purpose: Replaces old, worn, or corroded spark plug wires to restore strong, consistent spark. Fitment: For V8 GM marinized engines (305 & 350 CID) using Delco HEI ignition systems (1995–1998) . Kit Contents: Complete set of 8 red spark plug wires with pre-installed boots at the plug ends. Design: Each lead is custom-length to reach the correct plug location cleanly and securely. Durability: Built for marine-grade heat, vibration, and moisture resistance for long-lasting performance. Engine & Boat Compatibility GM-based V8 MerCruiser engines (305 and 350 CID) Delco HEI ignition systems (1995–1998 models) Used on sport boats, performance cruisers, and classic inboard/outboard setups Performance & Practical Benefits The 816608Q70 wire kit restores the clean, steady ignition your engine depends on. Each wire is engineered for low resistance and high conductivity, helping deliver full voltage to the plugs for faster starts, smoother idle, and stronger acceleration. The marine-grade insulation stands up to constant heat and moisture, while the red jacket resists cracking or fading. Because each wire is cut to fit perfectly, installation is quick — no trimming or guesswork, just match and snap them into place. Once installed, you’ll notice a cleaner-running engine and more responsive throttle right away. Why Buy OEM Mercury’s OEM ignition wires are made to the same standards as their factory engines — tested for strength, resistance, and conductivity in real marine conditions. Aftermarket sets often miss on length or use materials that break down faster in heat and salt. With Quicksilver OEM wires , you get a guaranteed fit, correct resistance, and durability built for the long haul. It’s the same quality Mercury installs on their new engines, so you know it’s made to last. FAQ Q1: What engines fit the Quicksilver 816608Q70 kit?

A: A complete set of 8 red spark plug wires with pre-installed plug-end boots. Q3: Are these wires safe for saltwater use? A: Yes. They’re designed with marine-rated insulation to handle salt, heat, and vibration. Q4: Can I install them myself? A: Absolutely. The wires are pre-cut and labeled for easy one-to-one replacement — just match the old wire and push the new one in place. Q5: Why choose OEM over aftermarket? A: OEM wires fit correctly, perform better, and last longer under marine stress. Aftermarket versions may use weaker insulation or incorrect resistance.
