So could I fit a 50mm zzp bov on treadstone intercooler piping? And if I were to get intercooling piping, would I need to get upper and lower piping?

 

well check the description of the piping when u buy it, if u buy it with a bov flange it will tell u what size bov will fit. and no u don't need to buy upper and lower, but I would anyway, just to get ride of plastic pipes.

 

It just says that it's flange is meant for a certain type of bov. And is it hard to replace the intercooling pipes?
