Product Description :

Upgrade your Triumph Trident 660 or Tiger Sport 660 with the K&N TB-6621 High-Flow Lifetime Engine Air Filter, engineered to deliver improved horsepower, enhanced throttle response, and superior airflow performance.

Designed specifically for modern Triumph 660cc triple-cylinder engines, this premium performance air filter maximizes airflow while maintaining excellent engine protection for both street and sport-touring use.

The K&N TB-6621 features multiple layers of high-grade oiled cotton gauze media that provide significantly higher airflow compared to OEM paper filters. Its pleated design increases filtration surface area, resulting in improved efficiency and longer service intervals.

Each filter comes pre-oiled and ready for installation with an application-specific sealing bead for a precise OEM fit.

Whether you're commuting, touring, or enjoying spirited riding, the K&N TB-6621 delivers smoother acceleration and improved engine responsiveness for your Triumph 660 platform.
