Are you washing the engine bay or playing it the water/ off roading?
What kind of COPs do you use for replacements?

Nothing will last as long as Motorcraft COPs!
How often are they going out and all of them or just certain ones?

There is a lot of people that have a problem with water leaks.
Sometimes the sealer under I think the wiper cowl leaks.
Also the heater hoses where they connect to your firewall are a well known problem.

How are you determining the coils you are replacing are bad?
