single plane intake manifold
Dual plane- these are stock on most cars. They interrupt flow and have longer runners and flow less air. They are good for making low end torque, because air turbulance = torque. LS1, LS6, and FAST intakes are dual plane.
Single plane- typically dont come stock on most cars. They are for racing and have very little provisions for torque down low. They have a straight thu design, short runners, and designed for maximum air flow. This would be a sheetmetal intake or a victor jr type intake.
