A few things - the 3.5 ecoboost has been around since 2011 (2010 - other platforms), and those owners fought through the problems to generate the weep hole fix themselves. With all the people that did that over the years, not one person has had a warranty denied for it. The Gen 2 of the ecoboost still retains the same design as the Gen 1, but the 15+ (15/16 still part of Gen 1) got the active shutters in front of the intercooler. This was to mimic the block off plate TSB that sort of worked on a previous Ford attempt to fix. These owners still had misfires and the rule of thumb on the ecoboost is to just drill the holes to prevent any potential misfire issues. This was really the problem that plagued the engine... Nevermind the high risk cam phaser failures. So, with all that, over all these years, no warranty denials. Plus, you have a bit happier ownership experience. A side benefit is that your plugs are not fouling and you will have increased mpg, plus not need to change plugs as often (get maybe 50k-60k miles compared to 30k miles). So, no negatives with this. I am very surprised that many here can't wrap their brains around this. It really is simple, and very beneficial to you. The aftermarket warns about water buildup in the intercooler, and has designs to get it out (VTA BOV, intercoolers with the weep hole already in it). Be open minded and think it through... I am trying to help, not push people to something bad. It is definitely a change in mindset for the turbo crowd that is used to other little turbo cars.
