i guess asking a parts guy would be best so, Rippy, what other gms use the same oil filter as the cts?
more specifically the 3.2L?

im curious because i know its not all that common but gm doesnt re invent the wheel when they dont have to so something else has got to share the filter.
i also question if mr lube is actually changing the filter out if i go there again...ive got oil and a filter but no time.
