R8 coilpack and NGK sparkplugs

[M22RJX]

Just wanted to know is it worth me spending £140 to get the
Above or am i better just keeping the stock omes
In??

Recently bought the car and already done a few bits
4x new tyres
Rear break pads
Tracking
Resonated cat back with miltek 35edition tips

Car feels like it has a map on there so wasnt sure if changing these other bits would help as eventually i want to turbo back my exhaust and take it to rtech for the stage 2 map

Also wondering the same. I'm going to replace my plugs just for standard maintenance, but wondering if it's worth doing the coils as preventative maintenance at the same time. No issues, and my car is standard.
