HIGH-FLOW STAGE-2 AIR FILTER — GEN 2

The MotorMad Performance Gen 2 Secondary Air Filter is designed for KTM riders looking for improved low-end response and mid-range performance without changing the overall OEM mounting arrangement.

Replacing the restrictive OEM secondary air intake cover with a dedicated filtered intake allows increased airflow through the secondary air system while maintaining filtration against dust and debris.

The filter housing is designed around the OEM mounting points, making installation straightforward and keeping the fitment clean and secure.

Performance Focus

This product is designed primarily for low and mid-range performance, rather than top-speed gains.

The increased secondary-air intake airflow can help provide:

* Better low-RPM throttle response
* Improved mid-range pull
* More responsive engine feel
* Improved airflow through the secondary air intake

This is not marketed as a top-speed upgrade.

Actual results may vary depending on the motorcycle’s engine condition, intake and exhaust setup, ECU calibration, fuel and riding conditions.
