Anyone have the black short ram intake that ebay sells? I bought one about 2 months ago and have had nothing but trouble. My mpg went from 15.1 to 12.3 when i put it on. I bought an extension and put it further in the fender well so it would get more airflow and is now up to 13.5mpg. Is there a reason it would do this? Does anyone know if more airflow will affect the ecm or ecu?
