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 exercise can be used in isolation for the purpose of rehabilitation or if it is used as part of a specific condoning program like that for skiing. To get the best results from the exercise it should be used in conjunction with other exercises like walking lunges or other leg exercises. The primary benefits of wall sit are; 1) Building up isometric strength after a knee operation as part of the knee rehabilitation process on the road back to full functional activity. 2) Any sport that relies on being in a position of hip and knee flexion for extended periods of time like skiing will benefit from doing walls quads as part of their conditioning program pre season.
