Jeff,

If the specs for the manifold did not change, then why is there a different part number, and more importantly, a significant price increase from 98 to 99/00?

The 98 UIM part number is 1S7Z9424FA and lists for $415.68. This ran through 5/2/99*

On 5/3/99 the part number changed to 1S8Z-9424-AA and lists for $804.10.*

If they truly were the same specs, then there would be no need for a part number change, and certainly no need to double the list price.
