D&J has found that some of the intakes with side entrances force air into the cylinders across from the inlet pipe, additionally, cylinders across from the inlet run 300-400 degrees hotter; In some cases even melting pistons. Since this intake utilizes the factory air intake mounting this allows the air to disperse equally throughout the entire intake manifold. This also saves the customer time and money by utilizing their current intake horn.
