Good evening all. I am looking to purchase a cold air intake system ASAP. I am willing buy new or used. I am not sure what I need. Spacer? Z-tube? I have an 03 coupe AT. Any advice on this would help. Thanks in advance.

 

AEM is probabely the best known cold-air intake but there are also pop-chargers and other ones you can look at

 

What spacer? The plenum spacer is something different and has nothing to do with a cold air intake.

In all honesty, all well know, name brand CAIs are going to be roughly the same, maybe 1 or 2 HP differences. Can't go wrong with AEM, Stillen, Injen, or any other of the 50 million on the market. I WOULD stay away from and of the generic eBay versions though. They probably work just as well but it's too much of a gamble.

 

Call Jason/Tony at Riverside Infiniti 1-800-919-8130 and they'll hook you up
with what I've been running for three years Stillen air-box and Z-Tube. That
should get you started....it's the best bang for your $! Takes about 15 min.
to install, and you'll love the sound......

 

I have the injen sounds the best imo

 

i have AEM and i like it

 

You should PM "vstrizheus" he has an injen for sale, he's a good dude.

 

We are trying to get rid of a Injen cold air intake here for cheap! If you need an intake spacer, exhaust, anything....PM me.

 

had aem and now have nismo.. had aem on my 350z as well but like the nismo best so far but kinda pricey
