When Nissan planted the powerful VR30DDTT 3L V6 engine with twin turbochargers in the Nissan Z, there wasn’t much room left in the engine bay. The cramped area didn’t allow enough space to accommodate the traditional top-and-bottom-split airbox design, so they created a unique single-piece airbox with vertically inserted panel filters that maximized flow while minimizing size.
As enthusiasts and engineers, we tipped our hats to appreciate the work Nissan did with this design. But we couldn’t help but ask ourselves—how can we make it even better?
