Hayabusa Air Box 08-21

Manufactured with 100% aircraft grade epoxy pre-preg carbon fiber with no fiberglass or other materials sandwiched in between. While other inferior airboxes have multiple issues with balancing airflow and actually lose horsepower, independent dyno testing shows this new airbox produces four horsepower over stock and five horsepower over other brands. As an added advantage, it is four pounds lighter than the OEM part. Two custom molded urethane air tight transition seals with computer designed roll over sealing lips provide smooth internal transition from frame to airbox. Improved airflow is obtained due to the open designed bag formed interior surface and 64% larger air inlets. Airbox can accept stock air filter.

We also have a version of this airbox that is made to fit onto Gen 1 throttlebodies:  https://montgomerymotorsports.net/products/copy-of-hayabusa-air-box-08-21
