Looking for the steel fitting that screws on and holds the aluminum sandwich adapter/cooler on engine. Behind the oil filter. Maybe looking for 2
Thanks

I have a RJC biggie oil filter adapter.
I have included pics to show the difference in it and a stock adapter.
$35 shipped to lower 48, PP to FF or add the fee.

Yeah I want to stay with the stock size , extra capacity filter like an ac Delco pf52. Not looking for the biggie adapter . But thanks. It’s for my 3800 series 2 car and there is limited space for filter.
