I'm piecing together an oil filter remount kit for and I'm at the fittings portion. The ports on the adapter plates are 1/2" npt on them. I can get hydraulic hoses made insanely cheap. Would it be best to convert these to AN fittings? What's the largest I can use for hose size? I'm also looking at adding a thermostatically controlled oil cooler. Do we even need those on our cars for daily use with very limited autocross usage? Thanks in advance.
