Max-Fire Ignition Coil Oil Filled - Red

The Max-Fire Ignition Coil Oil Filled - Red is a high-performance replacement coil engineered for enthusiasts and mechanics seeking reliable, consistent spark delivery in street and modified applications. Whether you're rebuilding a carbureted classic, tuning a high-revving engine, or upgrading ignition components on a performance platform, this oil-filled canister coil provides the electrical stability needed for demanding driving conditions. Designed with a female socket configuration, it integrates seamlessly into traditional distributor-based ignition systems where precision spark timing directly impacts engine performance and throttle response.

Built with an oil-filled design, this coil maintains optimal operating temperature and reduces voltage breakdown across the secondary windings—critical for sustained performance under load and heat cycling. The 0.45 ohm resistance specification is engineered to match classic and modified ignition systems that require precise impedance matching for maximum energy transfer to the spark plugs. The red powder-coat finish provides both corrosion resistance and easy identification on the engine bay, while the compact 3.9 x 3.9 x 6 inch dimensions allow flexible mounting options without compromising under-hood space on tight engine bays. At 1.65 lbs, the coil is lightweight yet robust enough to withstand vibration and thermal stress inherent to performance applications.

This coil excels in single-distributor carbureted engines, vintage muscle cars, custom hot rods, and any vehicle running mechanical or electronic breaker-point ignition systems with female-socket compatibility. Mechanics and DIY builders appreciate the oil-filled construction for its reliability in extended idle and wide-open throttle scenarios where temperature stability becomes non-negotiable. Installation is straightforward on existing setups—simply disconnect the old coil, mount the Max-Fire unit to the original bracket or firewall location, and reconnect the primary and secondary leads. Always verify socket type and resistance compatibility with your specific ignition control module or points-and-condenser system before purchase to ensure optimal performance and longevity.
