I use mercury racing ones now. Which oil filters do you guys like and why???

For a stock engine I like NAPAs

Roby

K&n

what about the fram hp4 any good???

I recommend Fram. I have always used Fram for many years on Merc stern engines. [black or blue]

AC Delco PF1218. Cheap and good quality.

Just like your wife

Mobil 1 M301. Uses a synthetic material for the filter element that won't swell up if it gets a little moisture in it.

No, wife is much more expensive.

I use the Purolator (don't remember the number off hand). They match the blue color of the HP500's. Read somewhere (may have been OSO a while back) they were good filters, so why not have them look good,too.
