DRY-CON Panel Filter

The GrimmSpeed DRY-CON Panel Filter is a high-flow, reusable drop-in replacement for the factory air filter on the VB WRX. Designed as a direct OEM replacement, it improves airflow while maintaining excellent filtration—without requiring oil like traditional performance filters. This makes it a low-maintenance upgrade that avoids the risk of MAF sensor contamination commonly associated with oiled filters. Unlike full intake systems, the DRY-CON panel filter offers modest performance gains but improves throttle response slightly and enhances turbo induction sound without affecting reliability. It’s a popular first mod for owners looking to stay close to stock while optimizing airflow. The filter is washable and reusable, making it a cost-effective long-term upgrade over disposable paper filters.
