The Weapon R Stealth Secret Weapon intake for 1986–1991 Honda Prelude Si is a vehicle-specific cold-air kit finished in gunmetal with a black filter element. It replaces the stock airbox to refine intake airflow and provide a more pronounced induction tone while fitting into the factory engine bay location. Designed for direct-fit installation on Prelude Si models, the kit offers an accessible upgrade path for improved throttle response and intake sound.
