K&N Performance Air Filter
This is an ultracompact K&N air filter that is designed to fit into tight places. It has a large 4″ outlet size so it is well suited for clamping directly to a GT30R or GT35R turbo. The compact size is a must when installing in a tight engine bay like the Lotus Elise or Toyota Celica. MWR uses this filter in our larger turbo systems for these cars.
