Yea they were pretty pricy, about 50 from advance auto parts, and no i havent put my 180 tstat back in yet, ill do that today since im wrapping my headers anyway, and i havent put the pully on yet but im going to a 3.4 because my buddy has on on his girls car but it only has a pcm and a downpipe on it and runs like hell so im giving him my stock one.
