I have a injen cold air intake on my mitsubishi galant 2.4l I4 auto, and with winter coming up I was going to switch to short ram im just wondering if launch would improve if the air takes less time to travel.
On a cold start, the throttle response for a short ram is much better than a cold air under any conditions. A good short-ram maintains good airflow velocity, as opposed to a cold air, with its longer piping. Once the engine bay heats up, the short ram loses a bit of its edge as the air is less dense, leading to less power. However, as I mentioned, on a completely cold start the short ram can give a pretty ridiculous launch. I'd recommend it over the cold air; the overall power difference is negligible, to be honest, and the cold air comes with more risks: Hydrolock, filters are lost easier, etc. And in my opinion, a short ram just looks much better anyway.
