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??
