Question about intakes for swapped motors, TB's, and IM's
 

This may or may not be a stupid question but I'm concerned about my current intake setup and whether it will function or not with a swapped VQ35 mated with a '00VI. The Injen CAI is for a '97, with '97 USIM that has a .55mm or .50mm? TB. Since I will be upgrading the VI, as well as the TB, the size will be then .70MM, it will be a Pathfinder TB. Will my CAI still fit, and work as usual with the larger diameter TB? Thanks.

the CAI you have is not a CAI. And if you put the VI on, the TB will be farther back than the USIM, so it will not sit in the same place as before.
