We seen instances where people removed boxes, batteries, etc. from the engine bay and certain areas got hotter than normal. My strng suggestion to everyone is to do "REAL" research before trying mods like this. Its similar to guys who increase intake ducting side for more "airflow". Great job because they just decreased intake air velocity.
