Today i was looking at some ignition coils, and i noticed that different brands post what the primary and secondary resistances of there coils are. Is it better to have low primary and secondary resistance? what does it mean to have a low or high primary or secondary resistance? like for example the mallory canister coil the chrome one has a primary resistance of 1.4 ohms and a secondary resistance of 10.0 ohms, the taylor coil has a primary resistance of 0.7 ohms and its secondary resistance is 4.7 ohms. Out of curiousity i pulled the coil off my engine and tested it, its a borg warner select ignition coil that i got from oreilly auto parts and it came with a life time warranty, the primary resistance of my borg warner is 2.0 ohms and the secondary resistance is 9.83 ohms. What is a good number of ohms to have on a coil? and what are the differences between ohms in a coil? does a lower or higher resistance give more power to the ignition or give more spark? this is something i know nothing about so just curious to know.
