Well Andy’s up and running again, I dare say Andy will explain the initial problem (How the hell you can fit the head up side down I don’t know) One thing I did learn from him which I didn’t realise before is that when # 1 sparks so does # 6. The 7M-GTE engine has bank of three coils, the coil on the left connects to leads 1 & 6 the middle coil connects to 3 & 4 and the right hand coil connects to 2 & 5. When # 1 sparks so does # 6, but # 6 is a wasted spark and does nothing. The same applies to the other coils they spark in pairs but one of them will be a wasted spark. Toyota in there wisdom referred to # 6 for the strobe pick up, this saves removing the coil cover that obscures # 1 lead; as they both spark together, it all makes sense now. Firing order just in case someone needs it 1-5-3-6-2-4

Those coil packs don't look fun to me.
They look more pricey than the standard dist cap and rotor.
Plugs and wires cost the same.

What's the life expectantsy of a new oem set of those and what do they run, american if you please.?

Hi ddmcse I have edited the original picture so you don’t miss it next time; you will need to refresh your cache (delete your cookies) some computers will hang on to the last image in the cache even though it doesn’t exist on the website, you may still see the old image with the yellow arrow.

I haven’t heard of anyone needing to replace theirs, so I assume they are fairly reliable. Toyota lists them as three separate part #`s, but you may need to order all three together. At a guess I would think they must be about $250 plus for all three. The best option is to buy them from ebay. Ebay 1 and Ebay 2 if any of the coils where faulty you could always swap them for one of your existing coils, that’s providing all three didn’t go down.
