The original kit comes with 4 pipes. As is common knowledge this kit doesn't fit without cutting one of the pipes from the throttle body to the FMIC, thus there are five pipes and 7 couplers in this kit.
One member asked if the TB pipe was missing looking at this pic above. It is there, it just isn't positioned correctly in the pic. It's the one with the BOV coming off it, outlined in red.
I don't understand, adapter? For what? Pipe to TB?
These fit fine, pipe to the TB has to be cut for it to fit correctly, otherwise, no issues.
BTW, last buyer flaked, this is still for sale. Sorry I was out of town for a while, then work got busy and I got sick. I'm on a slower rotation now. Have time to package and ship. Quotes for shipping are running around $50 for the size of this = thus local pickup preferred
