This is the carbon intake from Forge's B58 induction kit, sold without the inlet hose. It replaces the factory airbox parts directly. Carbon fiber doesn't conduct heat well, so it limits heat soak and keeps intake air temperatures down. The turbo gets cooler, denser air for better combustion.
What you get
- Carbon fiber intake that is strong, light and resists heat soak.
- Lower intake air temperatures than metal or plastic parts.
- Direct replacement for the factory airbox components.
Good to know
- Intake only. The Forge inlet hose is sold separately or as part of the full kit.
