JWT intake/pop-charger
Jim Wolf Technology intake systems, 50-state legal for emissions. DE, HR, and VHR variants are available. Aside from the 2006 OEM airbox, this is the only comparable intake in terms of power gain. Will produce a more pronounced induction noise compared to the OEM airboxes.
Heat shields are included and should be adequately sealed off from ambient engine bay air where possible to improve performance.
JWT know more about Nissan engines and the VQ platform than anyone else on the world, save for Nissan and NISMO's own development engineers. NISMO worked with them multiple times to produce racing parts for Z33 platforms, and JWT produce all of the IMSA engine builds for VQ-based GT race cars.
