DIY CAI

So what I'm gathering from all these posts is the hose i.d. is 2.5 inches and it's a 90 degree bend? Also I would need a 2.5 ss joiner and 2 breather hose connections?
 
Yes a 90 degree works, though I wish I had used a 120 degree radius. Some guys used silicone hose to make the turn and others, myself included used aluminum. The K&N 2570 is nice and small and easy to fit under the hood. A couple 1/4 barbed fittings work well for the vent lines.
