Another Truck Project

That is a cheaper type. There is plenty of the open air style but with mine I have a cold air sensor that mounts inside and a manual air restriction indicator, others have an electronic restriction indicator letting you airflow is struggling getting thru. Sensors will not be calibrated to this deer air induction system however they must be tied in to prevent a check engine code. Air filter is another option according to your area climate. I went with a dry filter (throw away) over oiled filter (cleanable)since we have a lot of dust blown around.
