I am doing EFI conversion on 16v. Do I need additional breather valve or can I just fit small air filter? 66504276_10217262822074097_7391906314353377280_o by 28619454_2073596225989531_8033893458948834548_o by
personally I would use an FPR and route it back to the intake as per OEM. You could use a breather filter but it would get clogged pretty quick so I would say if you want to go that route put it through a catch tank
