Other Corvette air filters use a simple pressure molded injection process to bond the perimeter rubber to the interior components. That method saves manufacturing time, but in the process, a considerable amount of rubber can seep onto the filtering surface. This can restrict airflow as much as 25%. Green Filters go through a precise 4 step production process, which virtually eliminates seepage and maintains maximum airflow through the filter. Other features of Green Performance High Flow C4 & C5 Corvette Air Filters include:
- A hand molded flexible rubber base
- Air tight seals
- Custom fitment tabs
- Deeper air filter pleats which creates 20% more filtration surface
- Race proven gains and technology
- Steel mesh coating for extra strength and durability

Green Filter
Green Filter USA has been building racing air filters for years. Eventually, as more people began using their street-legal cars for racing, Green Filter USA expanded into the street-car market. While many air filters have to be replaced and thrown away, Green Air Filters are designed to be cleaned and re-lubed with proprietary Green Filter oil. Zip is proud to feature Green Air Filters in our catalog.
