CAI Intake question

[NewPrixOwner666]

Ok, so Im trying to make myself a 4" intake, but when I went to home depot, the 4" PVC they had in 45 degree angle all came as either hub/hub or hub/spout(Or whatever it was) and also, the 4" went right over my TB, and was too big for the 4" - 4" coupler they had. Am I looking at the wrong thing?

If anyone had links to the products I need or something, that'd help me a ton

Just tighten the clamp down a lot!

the TB isnt 4", closer to 3.5"

kk, then how do I get it to be the size I want? All I have right now is crappy spectre 3"

Actually a 4" will fit just fine if you tighten down the clamp....

Trust me, I bought materials to make my own PVC intake and in my haste (Home Depot was closing) I bought a 3-3 coupler instead of a 3-4 coupler. Combine that with breaking the stock air box getting it out (long story) I now have the Spectre cone filter directly on the throttle body. It's not hurting anything but I have it on the 4" ring, I'm sure if I cut slits in the 3.5" one it would've fit but it was entirely too cold and dark for me to **** around with it anymore.
