Product Information
Full details
The Twin Air Air Filter (723.18.36) is designed for off-road riders and enthusiasts who demand peak engine performance without compromising on durability. By leveraging a specialized dual-layer, open-cell foam construction, it delivers an ideal balance of high airflow and robust engine protection against grit and dust. While it offers superior filtration compared to stock filters, riders should be aware that it requires a specific maintenance routine involving cleaning and re-oiling to maintain its high-performance characteristics over time.

FAQs
Can I use gasoline to clean my Twin Air filter?
No, using gasoline or harsh solvents can damage the foam and the glue used in the micro-binding process. Always use a dedicated air filter cleaner.
How often should I clean the filter?
The frequency depends on riding conditions. In extremely dusty or sandy conditions, it should be cleaned after every ride. In cleaner conditions, you can extend the interval.
Does the filter come pre-oiled?
Most Twin Air filters are shipped dry to allow the user to choose their preferred oil. Always ensure it is properly oiled before the first use.
Why is the dual-layer design better than a single-layer filter?
The dual-layer design prevents the filter from clogging quickly. The coarse outer layer traps large debris, allowing the fine inner layer to continue filtering air effectively.
How can I tell if I have applied enough oil?
The filter should be evenly colored and feel tacky to the touch. It should not be dripping with oil; if it is, squeeze out the excess with a paper towel.
Troubleshooting
Engine feels sluggish or lacks power
Check the filter for excessive dirt buildup. If the filter is clogged, perform a full cleaning and re-oiling procedure.
Fine dust found in the air intake boot
Verify that the filter is properly seated against the cage and that the sealing ring is not damaged or dirty. Re-oil the filter to ensure the foam is properly saturated.
Filter foam is deteriorating or crumbling
This is a sign of old age or exposure to harsh cleaning chemicals. Replace the filter immediately to prevent debris from entering the engine.

Setup, Compatibility & Care
To install the Twin Air filter, ensure the airbox is completely clean of any residual dirt before insertion to prevent contaminants from bypassing the seal. Proper installation requires checking that the filter seat is airtight against the airbox cage to ensure all incoming air passes through the foam media rather than around it. Maintenance is critical; clean the filter using a dedicated air filter cleaner, rinse thoroughly, and allow it to air dry completely. Once dry, apply a high-quality air filter oil, massaging it evenly into the foam layers until the entire surface is tacky. Squeeze out any excess oil to ensure the filter is not over-saturated, which could restrict airflow.
