2016 Hellcat Plum Crazy
Thank You for that info, I also have a 2021 C8 Z51, Just love those Vettes but for some weird strange reason that makes no sense I rather drive my Hellcat, must be the manual trans!JLT's CAI for the pre '19 cars comes with an optional plexi rain shield for that opening. The risk of water intake is minimal, but it does exist. Under normal driving, you're fine. However, if you park it outside and let it get rained on all day, it might get enough water in it to saturate the filter enough to ingest water and do some harm. The chance is exceedingly remote. I did the math on this topic a couple years ago and found that the standard filters can hold about 2 cups of water. To hydrolock the 6.2L, you'd need a quick intake of around 2 tablespoons that makes it into the combustion chamber. Remember that as water goes into the intake, it also has to go through the supercharger where it is super heated and typically becomes a gas. Even with aftercooling, not all of the water taken in will return to a liquid state. Most of that will pass without incident. But, with a super saturated filter, there is the chance of intaking more than 2 tablespoons of water in a situation like a cold start.
I don't know what the probability is, but it's very low. You'd need the perfect storm of absolutely soaked air filter, a cold engine, and a dose of bad luck to actually hurt the car.
