Moroso BB Chrysler Mopar 361/383/400/440 Str Plug HEI Ultra Spark Plug Wire Set - Red

If you're working on a big-block Chrysler Mopar engine like the 361, 383, 400, or 440 and need to replace your spark plug wires, this Moroso HEI Ultra set is a solid option. These wires are designed to handle the demands of these classic V8s, ensuring a strong spark gets to your plugs for reliable ignition.

Moroso uses a high-resistance core with a fiberglass braid and a silicone jacket to build these wires. This construction helps them resist heat and abrasion, which is important in the tight confines of an engine bay. The HEI style connectors ensure a secure fit onto your distributor cap and spark plugs, helping to prevent misfires and ensure consistent performance. The red color also adds a nice touch under the hood.
