After MONTHS of trying to figure out who was the member that made a DIY CAI....FINALLY!!... ok heres my questions, What Diameter is Z1 Post maf tubes not sure if they're 3 or 2.5"?? Also using the stock Air Box MAF location tube and having 3" in diameter before and after of course may require a tune but is there any gain with going 3" or sticking with a 2.5" diameter is a better option??

They fit a 2.5" OD pipe. So their ID is probably 2.65".

It shouldn't need tuned since the car will add fuel based off the MAF in the smaller tube. Will 3" add power? Idk. I'm boring out the TB's, manifold and lower runnings to increase air and hopefully power so maybe it will.
