9 At first glance, the intake manifolds look similar, but there is quite a difference in runner design. For your benefit, we weighed the two intake manifolds. The factory composite manifold with the stock CMCV plates and throttle body weighs 20 pounds, 11 ounces. The same manifold/throttlebody with the CMCV delete plates dropped to 19 pounds, 8 ounces. The C&L intake alone weighs in at 32 pounds, 4 ounces, and 35 pounds, 8 ounces with the single-blade throttlebody.
