yes, coil is built into distributor, and jacobs, msd, all need externail coils, i have a neuspeed thundersport which is plug-in so didn't need to cut any wires, along with magnecore and iridium plugs. I HAD bosch +4 platinum plugs, they were better than oem, but iridium plugs are the best... plus i returned the +4's for a full refund after 20k miles!!!
Problem with these systems is, they really do NOT give any extra hp than oem, but will SEEM better because anything is better than old plugs and wires. Honestly, ignitions are not worth it unless you plan to go turbo in the future or just have the $$$ to spend. I still don't believe that jacobs crap, more milage and shit, i bet if you just changed to oem honda wires and ngk plugs, you'll get the same boost in performance.
