This is the new "E-core" design replacement oil filter used in most GM LS-series engine oil pans manufactured in 2007 and later (excluding trucks and SUVs). It features an M22x1.5mm thread.
Please note this oil filter PF48E supersedes the original oil filter, part # PF48. PF48E is slightly shorter and has a plastic "E-core" internal core design.
