The AMS Performance air intake replaces the restrictive factory intake on the FA24 WRX with a full 3 in mandrel-bent aluminum pipe and a CAD-designed 6061 billet aluminum MAF housing with an integrated 4 in velocity stack, calibrated so the car runs without a check engine light. Four-ply silicone couplers with matched inside diameters seal the tract, and the rechargeable dry media filter cleans with compressed air and needs no oil. AMS publishes 15 WHP on the stock ECU and 25+ WHP with a Stage 1 tune. This configuration omits the enlarged duct and airbox, which are available separately to complete the cold air setup.
