Hi guys just thinking off a thousand things at once like usual and now are thinking about the coil packs.Is it worth putting them on the fire wall?and whats the advantage off doing this,apart from the heat side of things.

This question id like to know the answer as well.
From what little I know about this....If your running external bosch coils for instants you can run a stronger spark and as you have mentioned less radiant heat to cause the coil to drop, malfunction or fail.
The coils you get for the ca are good for so much HP and if you want to go aver that then your spark will be a limiting factor

Im looking at the splitfire coil packs,they run whats called DIS(direct ignition system)if u don't know what it is it where the ECU fires the coil directly.

Is that to eliminate the resister box thing? I have a set of bosch coils i got off wardy a while ago now and was planning to run the resister box thing in the cabin so its out of sight

Mate hopefully someone else can answer that for u,im a novice when it comes to the real technical stuff.

Heat is about the only advantage of running them on the firewall.

I would not bother spending money on spitfires or aftermarket brand unless your spark is breaking up at high revs, seems a waste of money to me.

Yeah that's true but I don't have any,my ca is bare and I need some so maise well get the good ones.

McDat- If you find the answer out regarding 'Is that to eliminate the resister box thing?'
Please share the answer. If it is the case il sell my bosch coils and get a set of spit fires. Do you know the spitfire amps and specs??? If similar i would rather a clean bay than add in 4 external coils

Still have to run igniter box, I have had both setups but most ppl run put holes in coilcover to let heat out then its neat

I had a chat to my tuner about coil up grades and he mentioned that he has run LS1 coils of a few RB powered vehicles with great success. They are cheap, realily available and pack a great punch. Mind you these vehicles were running Haltech computers.
