Actually, the OEM one has a ridge towards the end. I got CF piping from my old Monsterflow intake, but I don't think that you would want to pay $200 just for CF piping considering it's such a short pipe.BMWDon said:You're talking about the rubber tube between the maf and the throttle body, only once replacement I've ever seen is the injen intake system available now, they include a replacement tube, don't know the diameter difference inbetween the oem rubber vs. the injen, that would be the only reason I see getting it. It is ribbed on the outside, but the interior wall on the oem rubber is smooth I believe...not 100% sure.
Well, if you really want to get the CF piping, call Monsterflow and see if they will sell you only the piping. I paid $285 for the Monsterflow filter and the piping.rkaufman said:I am part of the current group buy for gruppe m's, but I wanted to make the entire intake and all piping carbon fiber.
