The maintenance side that you didn't take into account is the inexpensive side.Just curious, the link you sent says $60 per coil. Then you need to buy a high quality 6-wire set, right? Then you need a wiring harness to mate factory connectors to the aftermarket stuff. My math is $60x6=$360 plus a good set of wires is probably $80 or so ... call it $440 for the coils and wires ... then you still don't have the wiring harness. Electronics and what's capable aside, given PR and BL setups are under $500, not sure which part of this relates to "inexpensive"?
I don't. But given that's the point, how much does one R8 coil cost versus the MSD Blaster Direct Injection Coil?Same maintenance as any coil on a high powered motor, the coil and the wires, depending on setup. You don't honestly think they're just going to run forever, do you?
