Depending on stocks at the time of ordering the outer ridge may be orange or Black.. TELL US if its vital you needed a airfilter with black or orange outer ridge.. (as shown)..make no difference to function but for some people it might.
Suits but not limited to..& due to people changing things like shakers over the years.. check the height.. its NOT 3 inches.. yours may take a 3 inch one.. but this is specifically 2.5 inches.. and is discontinued by GM - this is an aftermarket filter.
