Free Spirits High Flow Bolt-on Air Filter Kit for Triumph Street Twin, Street Cup & Bonneville T100 from 2016. This new solution has been developed to significantly increase the air intake to the engine; providing better performance and lower operating temperatures. The kit includes a CNC alloy cap and clamp to firmly support our 52mm intake manifold and a water repellent SF filter. Airflow increases significantly, but thanks to the new engine management software's 'self-learning system', our tests have shown that there is no need to modify the original mapping, or additional units. It does not require the removal of the original airbox. Decreases engine temperature by 10 degrees. Quick and easy to install. Ready to install and complete with fitting instructions. As is the Free Spirits tradition, all modifications are reversible. Replacement parts are available for this kit. Innovative material and Zero maintenance. Sprint Filter is the only filter in the world made of water-repellent fabric that eliminates the passage of liquids, allowing use in harsh weather conditions.
