Curry Honda advertises the a-spec as 2002 to 2006, no distinction between years, and lowering of 1 inch. I read on an Acura forum, that the a-spec for 2005-2006,
said 10% increase over stock on the box, but on the 2002-2004, it did not say. I would think that they would be identical, no reason to change what ain't broke.
