I can testify that the Globals are very good and have a lot of power. I had a problem with my truck. It would buck when you got on it and downshifted, happened when trying to get on the freeway. Did it twice, so I started babying it to keep it from getting so violent. I ordered a set of the Globals and the day they arrived, I tried my truck again. It ran perfectly without me ever installing the COPs. Never another recurrance as long as that box of COPs were in my garage. I sold the truck, now have the COPs left. I guess I should call the guy that bought the truck and see if he needs a set of COPs. 
Maybe I should change my recommendation to, - purchase a set of Global coils, but what ever you do don't install them.

Nah, dirt, water or whatnots won't hurt it a bit. IF your greased the coil liberally and correctly. Greasing can be done wrong as well. If you don't grease they won't last that long IMO.

As most of you know...Bought an 8 pack from Global. After they were installed, it's idle was smooth I had more power, but still had vibration at certain RPM's, although not as bad.. Then it started to get worse..Idle went rough..etc..
I'm taking back to garage and have one of my old ones installed. They are going to do a
"Cylinder balance test" ? To find the bad one...
Sound right?
