So I believe my car is misfiring bad. Above 3k RPM I don't notice as much but around 2500 cruising the car stutters and definitely feels like a misfire. I changed the plugs from a NGK BKR7E to a BKR6E and gapped them at .034 it helped noticeably but didn't go away completely. A coworker of mine who said he used to be a big DSM guy said he had the same problem and changed his wires and it was gone. I was gonna go ahead and do the coil pack and wires together. I was leaning towards MSD. What are some suggestions for wires and coil pack to run with my plugs I have now and my 420a being turbod
 
use a oem coil, or granatelli coil and wires. those are the best, stay away from msd coils for the 420a.

ive had locals with srts and msd coils failing on them, theyre the same design as 420a.
 
yes the oem will handle the power at least thats been proven in the srt world but like i said theyre the same design as 420a. the screaming deamon is also good.
