the splash guard is prolly a safe investment, it's like $50 or less so it's even worth the piece of mind I think. hydrolock is basically when you get water INSIDE your engine. When your Intake
sucks up water into your engine, your engine then tries to compress it, as if it was air then injects gasoline and attempts to create combustion, however, water doesn't compress in an engine too well, and as a result nothing to much happens, as in... dead engine. Will it be a problem for you? Maybe, maybe not, all depends on how you drive your car in the rain. The MAJORITY of hydrolocks occur from driving through a deep puddle with an Intake
, if you just get some splashing the hydrolock can probably be fixed, however if the Intake
is submerged and sucks in a lot of water you'll probably be looking at either a total engine rebuild or a new engine.
