Just did the first oil/filter change on my new (about 10 hours) Z915B ZTR. Bought the JD filter that was called for (not an aftermarket) from an on-line dealer and noticed that they were different than what was installed from the factory. Part #'s on both were the same, diameter was the same, but the OEM on the left was taller than the replacement one. I'm assuming it won't be an issue.... just seemed weird. Thoughts?
