My Z4M warranty is about to expire and am wanting to do a few minor mods. A ESS tune and a RPI ram intake. Hope this does not sound like a really silly question but have anyone of you had the RPI Ram intake installed and driven through a heavy thunderstorm. Curious if the plumbing would allow water entry into the intake and cause a stall? I know you would have to be going pretty fast and it rain hard, but.........
