Iv'e had a look at previous threads on bov's but I was wondering how many different bov's actually replace the factory recircs, cause i don't want them in the engine bay. I had some in the engine bay but took them out cause I think they should be out of sight, but they are too small to clamp in the pipe where the recircs currently are. They are Turbosmart Type I with a 25mm end on them. And the factory BOV pipes are like 40mm or something. (Yes, I can hear you thinking, quad bov setup ) Well i just found out myself when i was installing my FMIC a couple of weeks ago. Previous owner must have been a bit slack. Thanks fellow zedders.
