To recap slightly, a cold air intake works by pulling in cooler more oxygen rich air while a short ram pulls in warmer air but at a faster rate.However, itâs very important to understand that because the intake is located near your engine, the air being pulled in is warmer than a CAI.
Wall sit exercise, side view. A wall sit is an exercise done to strengthen the quadriceps muscles. It is characterized by the two right angles formed by the body, one at the hips and one at the knees. The person wall sitting places their back against a wall with their feet shoulder width apart and a little ways out from the wall.
Strengthening your thighs can also prevent injuries such as runner's knee. This common injury, which often happens to new runners, is tied to a combination of weak quads and tight hamstrings and calves. Wall squats (also called wall sits) are the perfect exercise to strengthen your upper legs. Stand with your back against a wall, placing your feet about two feet out in front of you.
