Intake air efficiency is directly related to increased engine power. The DNA filter made in Greece is a high-performance filter that improves intake air efficiency just like a funnel. The filter is developed in-house based on the basic concept of higher intake efficiency, high quality, and long life, and incorporates many innovations not found in conventional filters, such as air flow, mesh intersections, fold height and pitch, material selection considering aging, and even filter oil with our original technology. The filter oil is also made with our original technology.
