I’ve got the upper part of the cold air intake from a Sentra SE-R Spec V (AEM). It’s the pipe that goes from the manifold to the MAF.
It includes all the clamps/hoses/couplers(in original unopened bag) including the MAF adapter. If wanted, Ill give you a used filter too - though you should be buying a new one anyway 
The reason I have it, my wife’s car was in an accident and the lower part of the intake was crushed. We had to buy the entire CAI, but all we need was the lower pipe and the filter (why not replace the filter while we were at it!). Figure maybe someone can use it, otherwise it will collect dust.
