NISSAN INDUCTION CONTROL SYSTEM (NICS) - Maximizing engine-valve efficiency.
	Nissan Induction Control System (NICS), boosts torque at all speeds by the use of a variable induction valve. At low speeds, the valve closes, creating a long intake port which increases intake efficiency, increasing torque. At high speeds, the valve opens, creating a short intake port that better suits the efficiency of air intake at speed, increasing torque for fast highway cruising. The engine also features the Nissan Direct Ignition System (NDIS) in which individual coils located directly over each spark plug replace the mechanical distributor, spark plug wires, and single coil of conventional ignition systems. This system provides consistent and reliable high voltage to the spark plugs for improved performance and longer life with less service.
