These Ford Performance M-12259-R301 9mm wires feature a spiral-wound suppression core for low resistance and minimum spark loss. They have tough silicone insulation to withstand high temperatures and voltage loss for minimum crossfire, and are highly resistant to fuels, oils, and solvents. Other features include 45 degree plug boots (most applications), stainless steel distributor cap terminals, and a coil wire (if applicable). The wires are numbered for each cylinder and have the "Ford Racing" script on them.
FAQ
Do high-performance spark plug wires make a difference?
Absolutely, investing in high-performance spark plug wires, such as the M-12259-R301 model, can make a significant difference in your engine's performance. These wires are designed to efficiently conduct electrical energy, ensuring optimal spark delivery to the spark plugs. Improved conductivity and insulation provided by high-performance spark plug wires contribute to better combustion, enhanced throttle response, and increased overall engine efficiency, making them a valuable upgrade for performance enthusiasts.
What are the best spark plug wires for performance?
The M-12259-R301 spark plug wires are an excellent choice for performance applications, specifically designed for the efficient routing of spark plug wires in a 351w engine. These wires offer superior conductivity, heat resistance, and durability. Other top-performing spark plug wires often feature advanced materials like silicone or high-temperature boots, ensuring reliable performance under extreme conditions. When selecting spark plug wires for performance, it's essential to consider factors such as materials, design, and compatibility with your specific engine type.
Does it matter what spark plug wires you use?
Yes, the choice of spark plug wires does matter for engine performance. Quality spark plug wires, like the M-12259-R301, can improve ignition system efficiency, resulting in better combustion and overall engine function. Factors such as wire material, insulation, and design can impact conductivity and heat resistance. Choosing spark plug wires designed for your engine type and performance needs ensures proper spark delivery and contributes to optimal combustion, throttle response, and power output.
Are all spark plug wires the same size?
No, not all spark plug wires are the same size. The M-12259-R301 spark plug wires are specifically designed for the 351w engine, ensuring proper fit and efficient wire routing. Different engines may require wires of varying lengths and configurations to accommodate the specific layout and cylinder arrangement. When selecting spark plug wires, it's crucial to choose the right size and design for your engine to ensure proper installation and optimal performance.
Specifications:
Are these for HEI or standard points?
Are these cut to your own length an crimp the ends or is it a pre cut set with the ends already attached? Thanks. Overview makes it seem cut your own, but reviews here an other places make it seem already pre cut with no custom ability?

WARNING: Motor vehicles contain fuel, oils and fluids, battery posts, terminals and related accessories which contain lead and lead compounds and other chemicals known to the State of California to cause cancer, birth defects and other reproductive harm. These chemicals are found in vehicles, vehicle parts and accessories, both new and as replacements. When being serviced, these vehicles generate used oil, waste fluids, grease, fumes and particulates, all known to the State of California to cause cancer, birth defects, and reproductive harm.
Tools:
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically treated lumber. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
