Upgrading your STI’s turbo inlet unlocks improved airflow, quicker turbo response, and more efficient performance. A high-quality inlet helps eliminate restrictions in the factory system, allowing your setup to breathe easier under boost. Here’s what you need to know to get the most out of this upgrade.

Cracks, boost leaks, and poor throttle response can all stem from the stock inlet holding your setup back. Upgrading to a high-quality turbo inlet improves airflow, durability, and overall engine efficiency.
