About Us


The Edelbrock #22716 Max-Fire Ultra-Spark 50 Performance's Spark plug wires are manufactured from highest quality materials to help deliver maximum voltage ensuring the ultimate performance. These wires have an extremely high EMI/RFI suppression along with a very low resistance to help deliver the most spark possible. They feature a heavy duty 8.5mm diameter silicone jacket to protect the Kevlar spiral wound core from heat, moisture and chemicals. They are engineered for high performance engines that need all of the voltage they can get for maximum power output. Made with wire leads that deliver a low 40 ohms of resistance per-foot for maximum EMI/RFI noise suppression. This makes them ideal for engines with aftermarket high performance upgrades that require maximum voltage. See application chart for engine or vehicle specific kits.

Installation Notes
  • Check your spark plug wires regularly! Like everything else on your car, spark plug wires need to be checked and require periodic changing. If you want to keep the performance of your engine at the optimal level, we recommend you replace your spark plug wires at the same time you replace your spark plugs. Fouled, damaged, or worn out spark plugs can lead to a variety of engine problems, such as misfires, hard starts, increased emissions, poor fuel economy and reduce acceleration. For most vehicles, you should replace your spark plugs every 30,000 miles.
