The Revision 2 High-Flow Airbox Lid provides nearly four times the air-inlet area of our original design, increasing available airflow to the engine. The integrated FrogzSkin® hydrophobic mesh helps repel water splashes, dirt, dust, and debris while allowing air to flow freely. Designed as a direct bolt-on replacement, the lid installs without drilling, cutting, or modifying your existing airbox components. This airbox lid pairs especially well with our CRF300L performance tunes. Important: FrogzSkin mesh is water-repellent, not completely waterproof. Avoid prolonged submersion, and always use appropriate caution when riding through deep water. Cleaning and Care Clean the mesh as needed using mild soapy water and a gentle stream of clean water. Do not use a pressure washer or direct high-pressure spray, as this may damage the mesh.
