Ive been running mine since 2019. It has never been wet after driving in the rain, spray, interstate speed. Im assuming Canadian rain is just as wet as US rain, but yall have some funky stuff up there.
Now the snow, I can’t speak a whole lot to. I live in a pretty temperate climate. The whole time mine’s been on, the AGS slats were removed too. I did also pay extreme close detail to the under hood sealing.
I can honestly say its a very effective ram air/cold air system.
I guess I could ask for my IAT stats to compare.
My truck sees 2*-3* above ambient while driving. I've since changed my Diablo to show Ambient and Intake temp on the same screen, but don't have a picture of that yet. But as the pictures show, 31* ambient and 34* intake.
