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.
One effective exercise is the wall squat. 1  Stand facing a wall with your nose and toes against it. 2  Squat down as far as possible with your arms hanging between your legs. 3  Perform 3 sets of 15 reps every day until you can drop your hips below your knees. For those who can't drop their hips below their knees after performing the wall squat every day for two weeks, focus on the front squat and single-leg squat for quadriceps development. The wall squat, however, is great for anyone.
