Details
These Billtet 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 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 applications with big HP gains in the upper RPM level. Direct bolt on.
Note: Two Gaskets that fit this piece : MMR-900878 & MMR-900876A
