Unlocking cold airflow to the engine drastically sharpens throttle response and amplifies the addictive, raspy induction roar of the 2.0-litre naturally aspirated F4R motor. Replace the restrictive factory airbox with high-volume Induction Kits for maximum cold air feed directly into the intake manifold, or choose drop-in high-flow Panel Filters for a clean, highly effective OEM+ breathing upgrade that fits perfectly into the standard housing.
