I don't use cones. I use an upgrade CAI. I have an AFE momentum air-box. Yes you sacrifice maybe 12 hp by doing so, but you create horsepower by running "cold" air to the turbos....

I know there's two schools of thought on this one. The hot air guys have the data etc., I'm not here to refute it or say it's "false news". I just like more cold air going to the turbos, which get hot as h@ll to begin with. This begs the question, why are we pushing more hot air to a part of the engine that is already extremely hot to begin with ?

Just food for thought.
