Spin-On Oil Filter Mod for 617???

[Diesel911]

I only noticed this Ebay Seller who is selling a service that modifies your own 617 Oil Filter Housing to take a Spin-on Oil Filter for about $220.

I do not see the benefit of doing this expensive mod unless there is a finer lower Micron filter that could be used.

It also looks like it could make the Oil Filter change a little more messy.

But, I would some opinions from others.
