Couldn't load pickup availability
Entering the final phase of development, our modular dry carbon airbox is compatible with R32/ R33/ R34 GTRs and incorporates improvements over the OEM box.
Constructed in 100% prepreg dry carbon, this part utilizes an 8-piece CNC aluminum mold and is autoclave cured for the highest quality composite construction possible.
Development included Computational Fluid Dynamics (CFD) to identify and reduce pressure drops and increase streamline flow, and included composite velocity stacks ensure airflow is optimized, resulting in increased performance. Dyno testing currently being completed; results will be posted shortly.
Available in gloss or satin UV clearcoat finishes.
Airboxes for R32 will include adapter brackets.
Ducting for R32 still under development and will be released in phase 2.
LAUNCH EDITION airboxes expected ship date: Early July 2026
