I completely removed that thing that I circled and have a small hose going from what I believe to the coolant to what I believe to be the throttle body. Instead of using that thing that I circled is actually a plastic hose with clamps that I bought from an auto parts store. Am I doing things right by not using the stock hose or the hose that AEM gave me? I couldn't connect the hose that AEM gave me from the intake pipe to the valve cover. I want to use the hose that AEM gave me because it is thicker and mine is really thin and flimsy.
