Can I use the 820s in place of the 910s with no ill effects on my focus? I'd like to add a bit more oil capacity. Is that the only difference between the two -- media amount?
Not compatible. The 910 is SAE thread and the 820 is Metric.
If you are looking for a larger filter, maybe you meant the 400S? that is the longer 910S.
Great! Thanks for the info. Cant believe I messed the topic/question up, and also doing a search netted the same results in another thread. Live (search) and learn haha!
