vs
Ignition coil MSD or APR
I purchased the MSD coil upgrade kit, swapped out the coil pack, new spark plugs / wires, fresh oil / filter. Fired her up and she purred like a kitten.
Pros: purred like a kitten
Vehicle:
Volkswagen Corrado
You can also spring for the MSD coil, about twice as much but the boots are attached better I think, where the OEM part might have the boots rip off or the springs get caught up.
Pros: boots attached better
Cons: twice as much
FWIW, I got an APR Stage 1+ tune on my '13 CC at about 30k miles. Blew one of the stock coils within a month. Replaced with red tops and new plugs and have been good since then (19k miles).
Pros: good since then
Cons: blew stock coils
Vehicle:
Volkswagen
Mileage: 30000 km
I replaced the coil with a MSD high performance which was actually cheaper than any other brand, and had significantly better boots on it to keep the water problem from happening again. Haven’t had an issue in 2 years.
Pros: cheaper, better boots, no issues
Vehicle:
Chevrolet Cruze
I got MSD Street Fire coils to replace mine and its been 4 months so far and they're running strong.
Pros: running strong
Vehicle:
Ford Crown Victoria
I have used the blaster w a stock icm (the inductive version) and also with a 6al (cdi version). Both worked well over for 400whp with a stock dizzy.
Pros: worked well, high performance
Vehicle:
Volkswagen Corrado
I ran a Blaster 2 on my old car for a bit. Idle was a little smoother, but it was probably because the coil on it was crap. No real performance gains expected.
Pros: smoother idle
Cons: no performance gains
I tried running them with the stock plugs awhile back and ended up with random misfires. Pulled them off and put the stock coils back on…no more misfires.
Pros: no more misfires
Cons: random misfires
Vehicle:
Audi S4
Please get rid of those APR Ignition Coils and RS7 Spark Plugs. You are most likely encountering the misfiring from those alone.
Cons: misfiring from APR coils
Vehicle:
Volkswagen Golf
I'd recommend getting rid of those APR coils before tuning, they cause so many headaches
Cons: cause many headaches
