I would really think for a road car standard coil pack and standard leads would be ok , as regards the 15% pulley dont fit it unless you have a proper remap done as well ,if not you will risk burning the top off a piston and that will be expensive .NGK BKR 7 EQUP spark plugs will help as well . best mods for a road MCS R53 are , 15% pulley . remap , modified airbox , plugs and then if you still need more go fit GP type intercooler and Janspeed manifold and sport cat and of course a new map to suit that lot . MSD coils etc are fine and work well but in my experience are not worth the extra money over std .
