a groupof original equipment parts and which is functionally identical of those original equipment parts in all respects which in any way affect emissions (including durability). (3) "Emissions

-related part" means any automotive part, which affects any regulated emissions from amotor vehicles which is subject to California or federal emissions standards. This includes,
