I got this Meth kit from a friend who had it installed on his 535. I've since sold my car and never installed it in my 335 while I had it. The kit doesn't come with the FSB or any of the tubing that runs from the trunk to the engine bay. I believe those are the only two things needed, but since I never installed it maybe someone more knowledgeable can chime in.
Because some pieces are missing I'm not listing a price. I'm open to reasonable offers and willing to ship given that shipping is somewhat calculated from my location.
Thanks and please feel free to ask any questions,
