It's a hybrid of hot and cold air intake so a warm air intake. Factory is actually a cold air intake as air is drawn from the front of the car. The car is now drawing hot air from the engine also. At speed you'll have more cold air from the front while at idle it's more hot engine air being the holes are closer to the filter. Hope your ECM can keep up and not go schizo. He loves me (hot) he loves me not (cold)
