SUMAX Spark Plug Wires - Blue 20634

Stock spark plug wires are a common source of ignition loss and heat damage under performance driving conditions. The SUMAX Spiro-Pro core delivers significantly lower resistance than carbon-core alternatives, which translates to cleaner spark delivery, cooler engine bay temperatures, and dramatically extended service life. If you're running electronic ignition or a classic points system, these U.S.-manufactured wires are engineered to handle the thermal and electrical demands of serious racing or spirited street driving.
