So basically heat is a big killer of dfi modules and coil towers, can mace make an insulator spacer and some longer bolts to solve this problem?? I would certainly pay money for something like this!

They generate their own heat, that is the killer, they get hotter than the engine does.

Oh okay I thought it might be heat sink, surely that could also be a factor?

Nope. By the time the engine gets to operating temp, the DFI and coils are already hotter. A decent set of aftermarket coils will not be affected by the heat as much as the genuine ones, but by the nature of electricity, the coils will always get hot.

Have looked into this before for the ECMs that are commonly found on the VZ Alloytecs as they're mounted direct to the engine. However have not looked into behavior of heat transfer between the ECM and the engine, same as the DFI module.

Kindest Regards,
