Yeah never really heard of those either, most use the billet oil filter caps with NPT fittings on the top.

 

ISSPRO sells them so they tell me, I also found a link to one in a different forum. Im waiting on the engineer from ISSPRO to call me back with all the part numbers of the fittings they are getting me. (Finding out the exact threads) then ill post up part numbers and all that good stuff.

Hey, thanks a lot!

 

no problem buddy

 

The only thing I just thought of though is that I hope the threads are the same from your year to mine.

 

Click the link MDUB posted and cal those guys. They told me those threads on the oil drain plug are the same for all 6.0's even the 7.3s. For some extra insurance you can double check!

 

Alright, thanks man!
