Oil Filter Thread Size?

[joem]

I am looking for the oil filter thread size. I believe it is 18 X 1.5. Anyone know for sure or where I can find the info? Thanks.:help:

I did some diggin' on this once before. No one could really tell me the answer of the thread size... closes I got was someone from K&N saying it was 13/16-16". I have no idea if that's right though, I've never measured mine with the filter off. Guess I should do that during my next oil change. However, what I do know is the type of oil filter... PH-8A... which is equivalent to the HP-3001.

probably didn't help ya... :dunno:
