BIG FATTY HD Intake Tube – Maverick R – RPM Powersports

The ultimate intake tube for Maverick R

The RPM Powersports BIG FATTY Intake Tube for Maverick R sets a new standard for airflow and durability.

Unlike systems that remove the factory airbox, RPM Powersports made a strategic choice: to retain the OEM Donaldson filter and original airbox, ensuring the best possible filtration to preserve engine longevity.

No aftermarket filtration separates fine particles as effectively as an OEM Donaldson filter.

🛡️ Retaining the stock airbox = protected engine

✔ Maintains OEM Donaldson filter
✔ Retains factory clamps
✔ Maximum protection against dust and sand
✔ Designed for extreme use (tested in Baja conditions)

Abandoning the stock airbox can lead to long-term issues.
The BIG FATTY was designed to prevent this.
