FAQs
Does this filter require grease on the seal?
No, the filter features a specialized greaseless foam sealing ring designed for a direct, airtight fit.
How often should I clean my Twin Air filter?
It should be cleaned after every ride, especially in dusty or sandy conditions, to maintain optimal airflow.
Can I use standard motor oil to oil the filter?
No, you should use a dedicated foam air filter oil that is designed to stay tacky and trap dust effectively.
Why is this filter smaller than my stock one?
Twin Air designs them slightly smaller to make installation easier and to increase dead air space, which improves combustion efficiency.
Is the filter reusable?
Yes, it is designed for multiple uses provided it is cleaned, oiled, and inspected for physical damage after every ride.
Troubleshooting
Poor engine performance/lack of power
The filter may be overly saturated with oil or clogged with dirt. Clean, re-oil lightly, and ensure it is dry.
Dirt found in the airbox past the filter
Check the seating of the sealing ring. Ensure the airbox rim is clean and the filter is properly secured.
Filter feels stiff or brittle
The material has likely degraded. Replace the filter immediately to prevent engine damage.
Pros and Cons
Pros
- Superior filtration of fine dust and sand particles
- Optimized airflow for improved throttle response
- Easy to install due to a compact design
- Reliable, airtight seal with the airbox
- Durable construction resists material separation
Cons
- Requires regular cleaning to remain effective
- Must be oiled properly before each installation
- More maintenance-intensive than disposable stock filters
Setup, Compatibility & Care
To install, ensure the airbox is completely free of dirt or debris before inserting the filter. Slide the filter into the airbox, ensuring the flat, greaseless sealing ring is properly aligned against the airbox surface. Do not over-tighten the mounting hardware, as the foam seal is designed to provide a secure fit on its own.
For maintenance, clean the filter using a dedicated air filter cleaner. Wash away all dirt, rinse thoroughly, and allow the filter to air dry completely. Once dry, apply a high-quality foam air filter oil, massaging it into the foam until evenly distributed. Squeeze out any excess oil—the filter should be tacky, not dripping. Replace the filter if the foam shows any signs of tearing, crumbling, or hardening.
