This new DNA hood and air filter kit for BMW R 1250 / GS / Adventure Stage 2 replaces the original BMW air filter and the "restrictive" plastic frame.

Designed to "sit" lower than the original filter, it frees the 2 airflow passages that direct cold air from the front of the motorcycle to the filter.
By gently directing incoming air to the lower airbox, we eliminate restrictions, turbulence, and improve torque and power.

With an active filtering surface of 132,300 mm², this air filter has an 80% larger filtering surface and 38.5% airflow compared to the standard replacement air filter.

Filtration efficiency: 98-99%

Product information:

DNA S2 Adventure shipping kit flow rate: 181.40 CFM (cubic feet per minute) @ 1.5 "H2O corrected @ 25 degrees Celsius.

BMW air filter flow rate: 131.00 CFM (cubic feet per minute) @ 1.5 "H2O corrected @ 25 degrees Celsius.

The increased filtering surface and airflow will significantly extend the filter maintenance intervals, allowing the user to travel longer before cleaning the filter.

Despite the new revolutionary design, the filtration efficiency remains very high at 98-99%, with 4 layers of DNA cotton.
