I  installed the Wolf remote oil filter on the left side of the firewall on my IV-P.  It was primarily to avoid the mess when removing the stock filter.  I would have second thoughts if I had to make the choice again.

First, there isnt much space available so that the bend on the oil lines gets pretty tight.  Second, once the lines are installed, tightening them becomes a work of art.  Third, the extra lines in such a tight space make it difficult to avoid chaffing.  Fourth, the remote filter adds at least four additional points for a possible oil leak.  Fifth,  I still have a mess changing the remote filter.

Finally, the remote filter plus the additional oil lines aint cheap and I still wonder what real advantage I gained with all that effort and expense.    Just one persons experience.
