WeaponR Intake System for the FR-S/BRZOverview: The Secret Weapon is short ram system with a heat shield. A cold-air feeder hose can attach to the filter. A unique double tube design is used in part of the intake tube. Analysis: The Secret Weapon intake showed some promise, but fell a bit short on some of the details. Mid-range performance gains were better than average. Unfortunately, the air-fuel ratio achieved at higher RPMs was too rich. The result was a drop in high-RPM and peak power.
