I have been looking on the demon tweeks website for a Mocal oil cooler sandwich plate I have selected for a Corrado G60, but it has given me too fitment sizes The Corrado G60 engine is in my Jetta, so I have no chassis number to look up. The fitments are: M16 oil filter M22 oil filter I dont know what this means if Im honest. Any ideas? Im using the standard genine vw oil filter with the nut on the bottom specific for the G60 Thanks
