I did the BBI coils and Denso PK20pr-p8.

No and I wouldn't use them in my American or Japanese car either...

Seriously, plug technology has come a long long ways - OEM emissions warranties and the PITA of swapping plugs on so many engines (not to mention sky high voltages to jump higher cyclinder pressures) have dictated moves to ever harder materials like Iridium that will not wear and allow for a VERY small electrode.

Coil Packs are tricky... stuff like the HKS DLI II and Sun Auto Hyper are common in the import and tuner industry. Don't knock the JDM stuff because Japan Loves Porsches.

The tricky part with Coil-pack replacement ... they don't always add much HP, but they are more reliable over stock in higher HP cars. Basically... the lower the ohm resistance the better the performance.

EVERYONE use to run copper plugs, especially race cars as they are cheap as hell to change. Race cars foul them, burn them and change them very often for races. Street cars don't, especially the long task on our Porsches so make sure you pick a good plug. Copper works just as well in my experience as long as its not breaking up but usually don't last as long as someone mentioned above. I use to run down the street to the local parts place and pick up NGK 10 Heat Range Copper race plugs for some really high horsepower Hondas for $2 a piece but they didn't last long in that application and eventually get carbon build up quickly.

Evo's and Honda's take very little time to changing spark plugs so why use expensive ones.
