High-Flow Replacement Air Filter for KTM Dirt Bikes by Twin Air

Protect your KTM engine from harmful debris while maximizing power output with the Twin Air Coarse Air Filter—a premium solution engineered for riders who demand reliability in demanding conditions like off-road trails or dusty environments. This dual-layer foam system combines a coarse outer layer that captures large particles like dirt and sand with an ultra-fine inner layer that traps microscopic contaminants, ensuring uninterrupted airflow to your engine while shielding critical components from damage.

Unlike flimsy two-piece designs prone to separation over time, Twin Air’s fused construction eliminates gaps between layers where dirt could infiltrate and restrict airflow—preventing costly engine wear from even pinhead-sized particles that might otherwise damage pistons or cylinders like tiny bullets. Its slightly downsized profile compared to stock filters creates extra air space within your airbox, boosting circulation for improved throttle response during high-demand riding scenarios such as acceleration on rugged terrain or prolonged high-speed runs.

Why Twin Air Outperforms Competitors
| Feature | Twin Air Coarse Filter | Competitor 2-Piece Filters |
|—————————|————————————-|—————————————–|
| Layer Integrity | Seamless fused design | Separated layers risk particle leakage |
| Cleaning Durability | Adhesive withstands gasoline/solvents | Adhesive may degrade after repeated cleaning |
| Airflow Optimization | Enhanced space for unrestricted flow | Restricted airflow due to bulky design |
| Engine Protection | Zero particle ingress risk | Allows contaminants into critical zones |

The thick, flat foam sealing ring ensures a grease-free airtight seal against your airbox while maintaining breathability—eliminating leaks without sacrificing performance gains. Ideal for riders seeking an easy-to-maintain upgrade that combines rugged durability with measurable power improvements on both street and trail rides, this filter is engineered to outlast and outperform generic alternatives while extending your engine’s service life under extreme conditions.
