I wouldn't waste your money. It's a misleading photo showing it sparks like that. You would need a much bigger IGN coil and even then it's only going to jump where it wants.
The gap looks huge too. At the claimed 3% and 5%, you wouldn't notice it.
I just installed NGK Iridiums in both my GTI LE RFI'S and it made a noticeable difference in starting and acceleration.
