When selecting a silicone or rubber intake hose elbow, accurate leg measurements are key to getting a perfect fit. The leg length refers to the straight sections on each side of the bend — measured from the end of the hose to the start of the curved radius. To measure correctly, lay the hose on a flat surface and use a tape measure along the inner curve, not diagonally across. Each leg (inlet and outlet) can vary, so record both dimensions separately. Knowing the exact leg length ensures your intake or intercooler hose connects securely between components without unnecessary stress or stretching, improving airflow and longevity in your turbo or air-intake system.
