1983 Honda CB450SC Nighthawk · Original Airbox Element Buying guide
The written application names 1982, 1983 and 1985 CB450SC Nighthawk models. One filter services the original airbox. Those are precise application and quantity claims, not a general fit promise for every CB450SC year, donor airbox or custom intake arrangement.
The motorcycle’s year does not identify an airbox transplanted during earlier work. Match the donor box’s element reference with the stated application. Preserve the specific listed years instead of expanding them into an uninterrupted model range or relying on a similar-looking intake.
The current listing covers the original airbox and does not describe a pod-conversion element or multiple-filter package. If that airbox has been removed, identify the changed filtration arrangement on its own terms before selecting replacement elements. No custom dimensions or adapters are published here.
The listing specifies one filter for the original airbox, with one supplied per order. Its quantity is tied to that airbox application rather than cylinder count. Confirm the fitted box uses 17211-447-000 before buying the single replacement element.
Identify the donor airbox’s application and compare its filter reference with 17211-447-000, listed for 1982, 1983 and 1985 CB450SC models. No element dimensions are published here, so similar appearance alone does not establish coverage for a transplanted box.
Identify the changed intake and its required elements separately. This listing describes a stock-type original-airbox replacement and supplies no custom dimensions or pod application. The motorcycle model alone cannot confirm that this element suits filtration equipment installed later.
