Aside from the e-3's looking like crap, take the bosch's back they are junk. I worked in auto parts for 4 years and saw more sets of Bosch platinum plugs come back than I can remember. Running platinums in a vehicle that wasn't sold with platinums has no benefit aside from making your wallet lighter. Get some champion coppers or NGK's.
Any kind of "gimmick" plug is a waste. Just like a throttle body spacer or a "tornado". E-3's, Bosch platinum 2's, 4's, split fire, etc....
And I agree you're getting water
In your cylinder for some reason.

NGK PLUGS are my favorite, they have always been good plugs for me, I run some octane boost cause I can't get any good gas around here, I also run some combo "heat" addative which helps dry out water in fuel, yes all gas has water in it, and it also has injector cleaner in this addative. I do not run them all the time or on every tank of gas, but about every third or fourth tank just to keep everything clean and burning right.

It's true if a car didn't come with these newer plugs they ain't worth crap. I'm ashamed to say this but I've ha the same plugs for a while now, she runs great Simone had no need to replace them. As for additives seafoam Is great and ever few oil changes I'll use mopar fuel injector cleaner and Mobil premium gas. And yes premium gas does make a difference with the detergents, it can be felt under the pedal. Treat your rig right and it'll

You guys will think im crazy but transmission fluid is the best additive. Saves from dirty injectors and helps eliminate the possibility of sticking intake valves. 1 quart in the tank everytime you fill up works wonders. And makes for a really clean piston/cylinder on teardowns.
