1966 Honda CB450K · Air Filters & Vent Filters Buying guide
The filter listing asks for the carburetor inlet outside diameter and notes possible jetting and tuning changes. It supplies one filter. It does not identify this pod as a replacement element for the original air box.
Check the actual filter mounting surface on each carburetor, especially where previous work has changed the intake. The product’s 49mm label does not describe the carburetor’s internal bore or provide the filter’s overall clearance dimensions. Compare the mounting point and available space as separate checks.
The listing warns that pod filters may require jetting and tuning changes. Decide how you will address that work before changing the intake arrangement. A separately purchased jet is not an automatic calibration for this filter, and the pod purchase does not supply a complete conversion or a stock air-box element.
The listing directs you to measure the outside diameter of the carburetor inlet for filter mounting. The internal bore is a different measurement. Check the actual mounting surface and then the room available for the filter body.
The mounting dimension does not establish overall clearance. The listing does not provide a full set of body dimensions, so compare the actual space and confirm any missing measurement before ordering for a tight custom installation.
The filter listing says jetting and tuning changes may be required. It does not promise that the existing calibration will remain suitable or prescribe a replacement jet size. Assess the installed carburetors and intake setup before making the change.
