yeah, some are lucky & some are not with the bosch units. i do however recommend using a bypass valve over a blowoff to recircualte the air back into the intake track. if you dont mind the overly rich condition flooding your cylinders when you shut the throttle then no big deal.....they do make better aftermarket bypass valves than the bosch units..........
