That's fair enough, we've all done it. You'll be quick to rip it back out when you realise your car runs like a bag of shit and tends to stall at lights etc. It will run rich as it's still compensating for air returning back behind the AFM when it's not. If you really wanna do it, Take the bov off and cut a coke can up to the same shape as the flange shape of the BOV and cut two holes for the bolts to go through, then sandwich that aluminium sheet between the intake crossover pipe and the BOV.
