Maximising cold air intake volume improves high-rpm efficiency and sharpens the response of the individual throttle bodies. Swapping the standard paper elements for high-flow Panel Filters provides an immediate breathing upgrade. For maximum air velocity, full Induction Kits remove internal restrictions and increase overall flow capacity. Combining these systems with smooth silicone Induction Pipes & Hoses eliminates turbulence, ensuring the 4.0-litre engine receives a constant supply of dense air while amplifying the mechanical induction sound.
