Maximising cold air intake volume to the rear-mounted 4.0-litre engine improves throttle response and top-end induction efficiency. Replacing restrictive factory air elements with high-flow Panel Filters represents an effective initial upgrade. For maximum air velocity, complete Induction Kits remove internal airbox restrictions and increase overall flow capacity. Pairing these systems with smooth silicone Induction Pipes & Hoses eliminates air turbulence along the intake tract and amplifies internal induction sound within the cabin.
