I want to "tread carefully" here and simply offer another insight, I'm not here to start arguments or tell people not to buy these. For anyone that has already decided that they want catch cans, these are beautiful, well made piece that I personally would probably buy... BUT, some people, included a highly respected tuner,
HERE, say that they simply are not proven at all to help against carbon build up, they suggest changing the oil frequently and only using Top Tier gas... Ford also upgraded the PCV system for '16+ model years to help further against carbon buildup, so for myself personally, I'm not going to bother with them.... Also, if spotted by the dealership, while they know they don't cause problems, they may look a little harder for tunes or other ways to void your warranty since it is a sign you are modding as noted in the service guide
HERE.
Again, I'm not here to thread jack, just put some info out there... These offered by Boomba are obviously VERY well made and high quality, I'd personally would buy these if I wasn't convinced that I don't think they are worth the investment.
