RHI Heat Shield Intake Guide
What is an RHI heat shield intake?
RHI stands for Rtunes Heat Shield Air Intake. It replaces the restrictive factory air box with a high-flow filter, intake tube, and a vehicle-specific heat shield designed to help separate the filter from direct engine-bay heat.
Why choose an RHI intake?
- Helps manage heat: The heat shield helps reduce the filter’s exposure to hot air from the engine bay.
- Improves airflow: A high-flow filter and intake tube can help the engine breathe more freely than the original air box.
- Sharper response: Many drivers choose an RHI system for a more responsive throttle feel, depending on the vehicle and setup.
- Vehicle-specific fit: Each kit is designed around the listed vehicle application for a cleaner installation.
- Performance sound: An RHI system can add a deeper induction tone under acceleration.
RHI vs. RCI vs. RSI
| Intake family | Design | Best for |
|---|---|---|
| RHI Heat Shield Air Intake | Open filter with a vehicle-specific heat shield | Drivers who want airflow upgrades with added separation from engine-bay heat |
| RCI Cold Air Intake | Longer piping places the filter farther from the engine | Drivers who prefer remote filter placement and are comfortable with a more involved installation |
| RSI Short Ram Air Intake | Compact piping keeps the filter inside the engine bay | Simple installations, tight engine bays, and a stronger induction sound |
