Radium Engineering PCV Catch Can Kit Fluid Lock WRX 22-26 | 20-0754-FL

Is an AOS or catch can worth installing on a stock 2022+ WRX?

A catch can is reasonable long-term insurance on the direct-injected FA24, especially if you plan to keep the car past 100,000 miles. A full AOS is overkill for a stock street car.
