The FireCore50 PF-3010 is a premium spark plug wire set engineered for Small Block and Big Block Chevy engines featuring a rear distributor and Pro Mod 45-degree spark plug boots. These 8.5mm wires are meticulously hand-built to exacting standards, ensuring precise fit and reliable function for demanding applications. Constructed with ultra-high temperature silicone jacketing for both the wire and boots, these sets offer exceptional durability and resistance to heat. The terminals are made from either stainless steel or solid brass, providing excellent corrosion resistance and a consistently positive connection to the distributor cap and spark plugs. Each wire boasts a consistent 50 Ohms per foot resistance, claimed to be the most consistent in the industry. When ordering, customers can select the appropriate Coil Wire Length from 5.00" to 50.00", choose between a 90-degree coil boot or a straight (180-degree) coil boot, and specify whether their coil has a male or female post terminal. Options for adding dielectric grease are also available to aid in installation and optimize performance.
