The Peterson Fluid Systems billet aluminum oil filter block-off plate for Chevrolet lets you connect wet or dry sump oil lines to the engine’s stock filter pad using a -12 AN inlet. It facilitates remote filter or cooler plumbing and includes mounting hardware and a -12 AN male fitting. Note: the stock oil pump passage must be blocked off during installation on standard Chevy V8 and bow-tie blocks.
