The MSD 8261 Ignition Coil is the top choice for racing enthusiasts using MSD 7 or 8 ignition control systems. This high-voltage coil is crafted entirely in-house, giving engineers complete control over its performance and quality. Its design features an iron U-Core along with a segmented bobbin that optimizes voltage distribution for better performance. The bobbin is made from Dupont Rynite FR946 material, known for its exceptional dielectric properties even at high temperatures. MSD has also integrated advanced winding materials that provide improved insulation and can withstand extreme voltages. This combination of high-quality materials results in a robust coil that delivers powerful voltage, rapid rise times, and extended spark durations, making it an essential component for anyone looking to enhance their racing performance. The MSD 8261 Ignition Coil ensures that your ignition system operates at its maximum potential, giving you the confidence to push your limits on the track.
