The Weapon R Secret Weapon intake is an aftermarket intake system for 2005–2006 Nissan Sentra 1.8L S applications. It replaces the factory inlet to provide a straightforward airflow upgrade for that engine, intended for street use where a direct‑fit intake is required. The design reflects a vehicle‑specific replacement that installs in place of the factory component and supports improved breathing and throttle response in typical driving conditions.
