The UltraPower Magnum High Performance Ignition Coil generates approximately 10% higher output than the factory ignition coil. The higher output will decrease sometimes imperceptible misfires. This is especially advantageous under heavy load conditions. These ignition coils are especially effective when combined with our UltraPower Magnum Spark Plug Wires!
