So , I bought a Golden Eagle sandwich adapter for my LS vtec line and turbo line. The interesting thing is that it will not thread onto the facoty oil filter stud coming from the block, granted I ahve a GSR oil cooler on it but , that should not matter. Doing a little looking around and testing, the honda filter thread pitch is M20 x 1.50 and the GE piece is a 3/4 x16 aka 19mm. I was wondering if any one else has had this problem? or are the LS posts a smaller diameter.
