These Gorgeous Billet Aluminum plates from MMR delete the factory plastic or cast aluminum IMRC (intake manifold runner control) which can cause an airflow restriction and a loss of HP along with gunking up of the port without the injector which leads to valve guide wear, smoking and oil usage. The plates can be ported and are great for all naturally aspirated and supercharged / turbocharged applications with big HP gains in the upper RPM level. Direct bolt on! Replaces both factory style IMRC plates (black plastic or metal versions)
