The DNA air filter for the Triumph Street Triple 660 S replaces the original filter and is designed to increase horsepower and acceleration while providing 98–99% filtration efficiency. It is reusable and can be cleaned, washed, oiled, and used again. Airflow is rated at 180.20 CFM, compared with 132.40 CFM for the original filter, an increase of 36.11%.
The filter medium consists of four layers of cotton between two layers of 5000-series aluminum mesh. The frame is made of polyurethane elastomer (PU), and the gaskets are made of EVA. The FCd design follows the contour of the airbox and increases the filtration area by 20–80%. The filter fits in the original airbox.
