DNA STAGE 2 PERFORMANCE AIR FILTER KIT – BMW R1250 GS / ADVENTURE 2019-23. Are you ready to take your BMW R1250 GS or R1250 GS Adventure to the next level of performance and adventure? Look no further than the DNA Stage 2 Adventure Expedition Kit. This kit not only replaces the stock BMW air filter but also eliminates the “restricting” plastic frame, allowing for a significant improvement in airflow, torque, and power. Key Features: Never Needs Replacing: Just like DNA’s other high-performance air filters, this kit is constructed from multi-layer cotton gauze and is oil-impregnated, meaning it NEVER needs replacement. This translates to long-term savings and ensures you have one of the best high-performance air filter setups available. Easy Installation: Installing this kit is straightforward. Simply follow the instructions provided in the BMW workshop manual, and you’ll have it set up in no time. Expansive Filtering Surface: This DNA Stage 2 Adventure Expedition Kit features an active filtering surface of 132.300 mm², which is 80% larger than the standard replacement air filter. This larger surface area, combined with a 38.5% increase in airflow, allows for better filtration and extended service intervals. You can travel longer distances before needing to clean the filter. Improved Airflow: The kit is designed to sit lower than the stock filter, freeing up the two air passages that direct cold air from the front of the bike to the filter. This ensures a smoother flow of incoming air to the lower airbox, eliminating restrictions, turbulence, and enhancing torque and power. High Filtering Efficiency: Despite its revolutionary design, the filtering efficiency remains exceptionally high at 98-99%, thanks to its four layers of DNA Cotton. This ensures that your engine receives only clean, purified air, even in challenging riding conditions. Versatile Performance: This DNA S2 application is suitable for both road and off-road use, making it ideal for adventure riders who want the best of both worlds.
