I don't quite get this mod.
Warmer air is less dense, I get that. Therefore the car would run leaner if it thought there was mroe air coming into the engine than expected based off the air flow meter. However, if I'm not mistaken, most cars have BOTH an air flow meter and an intake air temperature sensor that sends information to the ECU. So, if that were the case for this specific car, I don't see how this would help since the ECU would just correct accordingly and inject less fuel anyways.
Optimally you would want cold air going into the engine(to an extent) and the ECU to know how cold it is and how much there is to inject the correct amount of fuel.
Is there something I'm missing?
