Code No. 70026-AN004
Combining the stock air cleaner box with the “Carbon Duct” and the exclusive “Carbon Air Guide” offers a new intake system in a form never seen before!
【Concept】
- The Carbon Air Guide has additional fresh air inlets to direct fresh air into the additional ducts.
- With the additional modification of the stock airbox, the air intake opening area is approximately 1.8 times larger than the stock opening.
- Designed to reduce ventilation resistance, while avoiding any negative impact on the factory control.
【Styling】
- Utilizing dry carbon material (3K twill carbon fiber prepreg), expresses strength and sharpness.
- An overwhelming presence is created the moment the hood is opened, setting it apart Stock product.
- Combining the Carbon Engine Cover and the Carbon Fuse Box Cover (sold separately) will enhance its presence.
