I want to get a little more horsepower and gas mileage and I have heard mixed things about new intakes. I definitely do not want a cold air intake because if it gets wet it will mess up everything. I have heard from some people that short ram intakes do nothing and some claim that the 03 element does not have an air flow sensor and thus a new intake will not affect it. I thought that all elements have an air sensor and can be improved with a short ram. I need to know if this is true and also if I get a new intake, will I still need to replace the air cleaner on the stock intake?
