The cold air intake and throttle body do help they've increased my gas mileage by 2 if i drive like a granny. I can't get rid of my truck I love her too much. Anyways Frank what is better a tonneau or a regular cap? I can get a cap for mine 150$ but not sure if it fits, my truck has the stepside, or I can get a tonno for 250$.
