NEO is when the RB line went to the NEO Di (Direct Injection)

Here's a little info about it:
"By contrast, a direct-injection system allows exact control over not just the amount of fuel entering the combustion chamber, but when the fuel enters the combustion chamber. It even controls the shape of the fuel charge and the flow of air inside the combustion chamber! The benefits of all this precision can get pretty complex, but the short answer is that direct injection allows each tiny fuel molecule to be used with maximum efficiency, thus resulting in better horsepower and gas mileage. It also allows for a complete fuel charge burn, even when unburned exhaust gas is re-circulated back into the combustion chamber, which means reduced emissions and cleaner air."
