the coil burning issue as I have already told that local cng is the issue to coil burning but there is water is also a cause of the coil burning usually some ppl wash engine bay with water but if its done with hot engine it will suddenly cool the coil and will create some crack in it which will disturb current flow as suzuki coil are hell expensive so as altenate xli coil can all be used there is a cheap reparing thick is also there according to one pw memember we can fill the cracks with elfe and use irridium ik 20 plug to prevent coils from heating
Update
So i later found that xli coils shouldnt be use in any as additional coil will over load ecu as ecu is have only to drive tp fire to coil cheap OEM coils are easily available
