1967 coupe hood scoop

I doubt very much that any water that blows in through the filter is a significant enough amount to do anything more than slightly cool the intake air....some perspective on water locking:

I rebuilt an engine for a friend once that had a waterlocked engine...it was turbocharged with water injection....well, the check valve on the water injection system failed, it sucked the water in the resevoir(about a quart) into cylinder #4 and well, water does not compress like air....the connection rod was something like an S shape and the piston took a chunk the size of a quarter out of the bottom of the cylinder wall....but it took an entire quart of water ALL AT ONCE to do that...not to mention a direct path into the engine with engine vacuum pulling it through a hose. Combustion on its own produces water as a by-product of burning hydrocarbons....rain blowing in the front of an air scoop isn't going to water lock your engine....now, if you happen to have an 18 wheeler pass in front of you at a stop sign and kick up an entire puddle onto your hood and into your hood scoop...that may be something else entirely, but water is STILL denser than air...your engine is going to breathe the lightest fluid available to it unless it has no other choice...and that is air...that is why these work:



these "bypass" filters are built for cars with intakes that would otherwise be at danger of being water locked in the rain....if the main filter becomes submerged in water, they breath through the bypass filter instead. So how does this apply to you? simple...if you are worried about it...run a filter-lid setup, increasing the surface area your filter can breathe through....it will always chose air over water, its very unlikely you will ever surround a filter on top of your engine with enough water to kill the engine.
