Boat owners, if you're dealing with engine misfires or poor performance on your OMC, Johnson, or Evinrude outboard, these HeuroFosh spark plug wires might be exactly what you need. This 4-piece set features 6-inch wires made from durable stainless steel conductors and high-quality silicone insulation that stands up to the high temperatures and harsh marine environment. The construction ensures maximum spark delivery for better engine performance and fuel efficiency. These are direct replacements for part numbers 582365, ZF478V, 582134, 582135, and several others, fitting V4 and V6 outboards from 10-235 HP. The installation is straightforward if you're comfortable with basic engine maintenance – just make sure to replace one wire at a time so you don't mix up the firing order. The silicone material is flexible yet tough, resisting cracking and deterioration from oil, fuel, and heat exposure. I've used these on my 150 HP Johnson, and the difference in smoothness was noticeable immediately – no more hesitation at acceleration and much cleaner idle. The package includes everything you need for a complete tune-up, and the quality feels comparable to OEM parts without the premium price tag. Always double-check compatibility with your specific engine model before ordering, but if these match your requirements, they're a reliable, affordable solution for maintaining your outboard's performance all season long.
