09 Design HVF Performance Panel Filter
Unlock smoother airflow and a crisper induction sound while keeping your factory airbox. The 09 Design HVF panel filter is a direct replacement that fits perfectly and helps your engine breathe more freely for sharper throttle response.
Built with a lightly oiled synthetic cotton gauze called Hyperflow, it balances high airflow with strong filtration to protect your engine. A careful multi-stage build keeps the frame material out of the filter media, giving a clean, consistent surface and a larger effective filter area than many like-for-like options.
Expect a subtle performance uplift you can feel day to day, plus a deeper intake note under load. No ECU tune is required.
Key features
- Retains the OE airbox for easy fit and a factory-tight seal
- Hyperflow synthetic cotton gauze for high flow and reliable filtration
- Multi-stage construction minimises frame seepage into the media
Fitment

Why it matters
Better airflow helps the engine draw in air with less effort, which can improve response. Strong filtration helps keep dust and debris out of the intake system for long-term reliability.
