Product Description

The K&N KT-9907 is a high-flow replacement air filter built for select KTM motorcycles - including the 990 Adventure (2007-2013), 990 Super Duke (2007-2008), and various 990 Supermoto/SMT models (2010-2013). Its pleated cotton-gauze media significantly increases airflow compared to stock paper or foam filters, which enhances engine breathing, throttle response, and performance under demanding riding conditions - especially when accelerating hard, climbing steep terrain, or travelling long distances.

Installation is simple and drop-in: KT-9907 fits directly into the OEM airbox using a precise sealing bead, requiring no airbox modifications or fuel-system tuning for stock engines. Because the filter is washable, reusable, and backed by a long-life design, it reduces the need for frequent replacements and lowers long-term ownership costs. This makes KT-9907 a solid upgrade for riders seeking improved engine performance, efficiency, and durability - whether commuting on pavement, cruising long road trips, or tackling off-road adventures.
