I know there has been write ups and I've done tons of research what is the best intake to get I'm wanting the dual one with two intakes but wondering if the single cone is just fine I want to do some other upgrades but not right away as it's completely stock and only 3 owners and I don't want to cheap out on intake but if it's just 90° elbows or whatever 45° if there's a cheaper alternative for a dual one or is it best to just go with the Z1 package again I just got the car I had a z31 Na but not to familiar with these cars so please don't bash me.
