Coil replacement/ upgrade 2013

[ggranello]

I have a 2013 Abarth fine settimana car with 83,000 miles. It’s misfiring on startup. I changed the plugs (that needed doing anyway) but the cylinder 4 misfire has returned, so I’ll change out the coils. Anyone been thru this? Should I replace with stock or upgrade? Any suggestions re high-performance products? The prices for high-perfect are a bit shocking, are they worth it? If I choose hi-perf do I reset the spark gap? What is torque for plugs? Any advice on this job? Thanks for sharing your experience.

Probably easy to rule out if its the coil packs first.. Try swapping the coil packs (ie swap 4 with 3 since 3 has no misfires), if the misfire moves to 3 then you know it's the coil pack and I'd just replace all 4 with OEM ones, but if the misfire stays on 4 then you know its not the coilpack.

I've had a good experience with the Alfa 4C coil packs, if you want to go for it. They're not much more than the OEM versions, and they do add a bit of smoothness as you go through the power band.
