It is notable that our coils get corroded due to water entering the plug wells and being retained. Here is one possible solution, after trying it for 8k km in a tropical weather with thunderstorm weather and running through flooded streets....multiple times.
I have checked both most left and most right plugs and coils and no sign of corrosion or even water marks. These 2 plugs are the most notable for water ingress. As a reference, prior to this Orings, I did discovered my right most has water ingress, with brownish marks indicating water retention, plus a badly corroded HEX on the plugs.
Using O-ring to place in between the engine's wells opening and plug coil's "umbrella" (i hv no better word to describe). Shown below is the Oring in a pre-installed manner.
Below shows as installed.
The Oring is Viton material. Recommended to grease the Orings with high temp grease for better sealing. In my case use Krytox grease.
Dimensions: OD 33mm, thickness 2.95mm, ID 27mm ( measured with a caliper which is not the best tool for flexible things)
