K, what do you reckon the risks are of going through one of those gas station car washes with a PR CAI?
I know I should wash my car myself, but I don't always have the time... So how big is the risk of Hydrolock, assuming all of my splash guards are OK?

 

Just go and turn off your car.

 

Minimal, unless your filter is completely submerged, or you're driving through a very deep puddle. If you want to still be precautionary wrap it with saran wrap or shield it with something. But it shouldnt do any harm.
