I just wanted to get some opinions on the benefits of having a bov on the cold side or on the hot side… tried searching elsewhere but no luck so here it goes. Please choose a side and state a reason why.

Hot side… putting it on the cold side will make the BOV freeze/seize eventually due to cold air being released. This is especially true if you have a front mount intercooler. (The air on the cold side will be very cold)

put it on your exhaust, near the tip.

I’d find the old thread and resurrect it. It’s been covered before and these clowns decide to be a little sarcastic at your expense.
