Overview

The EPAuto GP159 Extra Guard Engine Air Filter is crafted for Toyota Prius models from 2004 through 2009. Its rigid panel construction helps maintain filter shape as air flows through, supporting steady intake and helping keep dust and debris from entering the engine. This replacement is designed to align with the Toyota Genuine part number 17801-21040 and is compatible with FRAM CA10159, making it a practical option for owners who want a reliable, straightforward swap during routine maintenance.

Why choose the GP159 for your Prius

• Compatibility: specifically built for Prius 2004–2009 models and aligned with Toyota Genuine specs.
• Rigid panel design: helps preserve airflow consistency and intake performance.
