Nitrous oxide decomposes into oxygen and nitrogen when under the high pressure in the cylinder. The extra oxygen helps burn more fuel and to increase cylinder pressure. nitrous = way more hp and torque. Some people may feel that this is a cheap way of getting alot of power, but in the end it comes down to whoopin other cars. I personally think its a great mod to have and don't think its cheap or fake in any way.
