Why this intake is a winning upgrade

The Momentum GT platform uses a unique filter-to-housing interface to maximise element size within a compact, sealed enclosure. The smooth, one-piece airbox keeps heat soak at bay while the auxiliary opening provides an extra supply of fresh air. Pair that with a carefully profiled, roto-moulded intake tube and you get less turbulence and more consistent MAF readings, translating to crisp throttle response and dependable performance on both standard and remapped B58 cars.
