I had managed to change the ht leads at my coils with success.
Its a bit risky job,but ok.The oem leads are glued to the coils with some kind of epoxy maybe(?).
I removed them and clean the hole,at the end inside the coils there is something like a spike.
Install the new ones with some high heat silicone-gasket silicone.
Everything seems fine for months now.
I wish i could afford some dynatec doils!
One mod i did these days,is i took the oem spark plug caps and removed the resistor they have inside.(i have allready ngk spark plugs)
After some internet research,you dont need a resitance spark plug cap when you have a resistance spark plug allready.
It seem to work better at low revs,but nothing sure yet,maybe its my mind.
