Apico Air Filter - KTM SX85 2004 SX/EXC 125/200/250/380 1998-2003 (1-Pin)

The dual-stage foam construction offers a balance between high airflow for maximum horsepower and superior filtration to protect your engine from dirt and debris.

For optimal performance and engine protection, it is recommended to clean and oil the Apico air filter after every ride.

No, this filter is specifically designed for certain KTM models: SX85 (2004) and SX/EXC 125/200/250/380 (1998-2003). Always check compatibility with your specific motorcycle.

It is best to use a quality air filter oil specifically designed for foam filters to ensure proper adhesion and filtration properties.

The foam should be uniformly coated with oil and feel slightly damp, but not dripping wet. Squeeze gently to distribute and remove excess.

A dirty or dry filter will restrict airflow, leading to reduced engine performance. It will also be less effective at filtering contaminants, potentially causing engine damage over time.

Verify that your motorcycle's make, model, and year exactly match the product's compatibility list. Ensure no obstructions are preventing proper seating.

Check that the air filter is correctly installed and sealed within the airbox. Ensure the filter is clean and properly oiled, as a dry or clogged filter can restrict airflow.

The air filter may not be sealing correctly, or it may require cleaning/replacement. Inspect the airbox for damage and ensure the filter is seated tightly. Clean the airbox thoroughly and re-install a properly prepared filter.
