Billetworkz 6 Speed Heartbeat Engraving Cosmic Space Shift Knob - Subaru STi 2004-2021 Color:Purple In tank designAll 6 Speed STI Shift Knobs are designed to replace the OEM shift knob and to have full reverse lockout functionality. These custom anodized shift knobs are truly one of a kind. Each shift knob is polished to a mirror finish before anodizing. During the anodizing process, all color combinations are done by hand using an intensive technique. The anodizing process builds a strong layer making the shift knobs extremely durable and scratch resistant.
