Very little has changed on the 2009 Apex and RS Vector models. That goes to show how well they perform. Perhaps the most significant improvement is the addition of a new rear heat exchanger at the top rear of the tunnel. This extra extrusion replaces the previous crossover tube from 2008, and increases the cooling capacity of the Apex and RS Vector models. This change should help keep the temp light from coming on, providing more consistent engine cooling and greater customer satisfaction.
