I think they both are very very similar.

I went with Nismo as it's a Nissan item.

They are louder than stock of course. They both have a hiss when sitting still. Other than that it's a toss up.

ok ive been away for a while. ordered the nismo CAI and tried to install it last night and it didnt fit in. im not by any means a solid machanic so i had my buddy come over and look at it this morning and he just said flat out that it isint gonna fit. the heatshield hits the small piping that comes out of the radiator. where i highlighted is what im talking about.

has anybody else had this problem on an 01? the pictures in the install didnt have that piping at all too. Does the 98-00 have that? or am i just special?

You should not have problems with the NISMO instal. I think that you need to post up some picks for us to assist.

I had mine installed on 2003. Your truck looks like a 2002-2004.

BTW: The pipe coming out of the radiator as you say is an AC pipe and does not come out of the radiator but goes to the coil in front of the radiator.
