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.
The wall sit adds resistance to the most difficult portion of the squatâthe very bottom. Bracing your back against a wall, you'll slide down until your thighs are parallel to the floor. Then, you'll hold this position for as long as possible. Maintaining this fixed position increases the time your muscles are under tension.
