In the middle of an oil change.

The filter that came out is a single unit - number HF161

Bike came with a spare oil filter but a two piece 11 42 1 337 575

From what I see, the new filter ending in 575 is for an airhead with an oil cooler - I'm not sure but am inclined to say my bike does not have an oil cooler.

Here's a link showing the options from euromotoelectrics

Real OEM fiche says the correct filter is: 11421337570 Looks like it comes with the O rings on both ends but I'll need to purchase a gasket. I'm pretty sure this is it.

Looking for confirmation!

Thanks as always
