Note– due to the various Mustang Ignition Systems and EFI systems we’ve decided to split this article up. This link will remain valid, and will host links to the new articles as they are brought online. Currently we’ve split off and updated the 5.0 and 4.6 mod motor section. The rest of the information for later cars will remain below briefly until we revisit this and spin it off into it’s own (improved) writeup.
We’ll be adding more sections soon to better support our customers with 4 and 6 cylinder Mustangs, as well!
