Thumper
Autocross Champion
Yup, Thumper did some testing and posted some charts. He didn't test the exact thing that APR is claiming (10% more energy over pulse width), but his results do prove that the APR coils performed better in what he tested. That's mostly what sold me on these. That, and they're basically the same price as legit R8 coils.
I heard from a buddy that there was some issues on the MK7 versions in the GTIs at high RPMs. Grain of salt, heresy and internet and all that. I can confirm no such issues present themselves on mine, they performed flawlessly at the track, seven 20 minute sessions (lightning canceled one of my sessions on Sunday ) and never a hiccup or issue, just strong pulls of power and instant throttle response.
