Weapon R wpn826-123-101

The Weapon R aluminum coolant overflow tank is a direct replacement for 2003–2006 Nissan 350Z models; it is explicitly noted not to fit HR motor variants. This machined reservoir offers a durable aftermarket upgrade for the exhaust‑cooled kit area, presented as a vehicle‑specific aluminum tank intended to match the fit and mounting of the listed 350Z years.
