Caveats and conflicts (2)

Chart codes are market specific; US/CA codes used. JDM and EU codes differ (e.g. TY856UB1KA JP STI MY08-14, TY856UG1MA EU). Subaru parts catalog (parts.subaru.com) is Cloudflare-blocked so no OEM catalog confirmation. Wikipedia lists TY856UW6AA for MY15-18 instead; chart splits MY15-17 (UW9AA) and MY18 (UW6AA).
