Cooler Intake Temperature Makes Horsepower

JEGS Cool Gap dual-plane intake manifold is more efficient and creates more horsepower than standard dual-plane models. This manifold's unique air space design under the plenum and runners allow airflow to pull off excess heat, decreasing the intake temperature and providing better fuel atomization for improved performance. The 4150/4160 carb flange accepts most non-EGR 4-bbl square bore carburetors; this cast aluminum manifold is available in satin and polished finishes.
