Blykins;

Normally a single plane intake will make more hp,but also at a higher rpm level,all depends on the total motor package,also single plane intakes usually lose a little hp and torque at lower rpms.........in a light weight Cobra a dual plane intake is all you need unless it is a dedicated race car.............

Also,you should get a better idle with a dual plane intake and they are usually not as tall as a single plane,some cars have a hood clearance problem with a single plane intake...............

Just general terms,I like the dual plane for a street car and use one and a single plane intake on my race car...........
