DescriptionThe whole story▼
Built from premium cotton gauze and engineered to last the lifetime of your engine, the K&N TB-6706 replacement air filter is a direct, no-modification swap for the standard air filter on the Triumph Daytona 675 and 675R. It unlocks the full potential of the factory airbox, delivering measurably improved horsepower and acceleration while remaining fully compliant with all noise and emissions regulations.
Key Features
- Premium cotton gauze construction provides high airflow combined with outstanding filtration, maximising engine output without sacrificing protection.
- Direct OEM replacement — fits straight into the existing airbox with no modifications, no remapping required, and full compatibility with factory vehicle electronics.
- Washable and reusable design eliminates repeat filter purchases, delivering long-term savings and reducing workshop waste.
- Engineered to last the full service life of the engine, with cleaning intervals of approximately 80,000 km depending on riding conditions.
- Protects the engine against harmful contaminants while meeting all applicable noise and exhaust regulations.
- Environmentally responsible alternative to disposable paper filters — one filter, one lifetime of use.
Build Quality and Materials
The TB-6706 is constructed around K&N's signature multi-layer cotton gauze filtration media, pleated for maximum surface area and oiled to capture fine particulates before they reach the engine. The filter frame is precision-formed to match OEM dimensions exactly, ensuring a secure, rattle-free fit inside the Daytona 675's airbox. Unlike a paper filter that degrades with moisture or age, the cotton gauze construction retains its structural integrity through repeated wash and re-oil service cycles — a clear reflection of K&N's commitment to long-service-life filtration engineering.
Performance on Road and Track
By reducing intake restriction compared to the factory paper element, the TB-6706 allows the Daytona 675's inline triple to breathe more freely across the rev range. The result is a more responsive throttle, sharper acceleration, and the sense that the engine is working with rather than against its airbox. Because the filter slots directly into the OEM housing, no fuelling changes are required — the improvement is felt immediately, straight out of the box.
