Give some more spark to your ignition system using these Professional Products LSX high performance coil packs. They provide a maximum voltage of 40 kV and the longest spark duration available. The coil packs fire 1/8th as many times as the old single coil systems, providing eight times as long for the coil to regenerate power for the next spark. On multiple coil setups like these LSX high performance packs, longer spark duration is highly desirable to ensure that 100 percent of the intake charge is ignited—for maximum power throughout the entire rpm range.
