Nice used California emissions air cleaner assembly, includes base with elbow, snorkel, heat riser and air cleaner lid. Application is any 1967 Mercury Cougar or Ford Mustang with C code 289-2V or A code 289-4V engines with closed emissions as sold in California. Elbow on air cleaner connects to the oil fill cap with a rubber hose. All good parts as shown, thermal switch in air cleaner snorkel may not work, and no we cannot test them.
Even if you are not currently running all original parts under the hood this is a great set to stow away as these items are going up in price and add value to your car when the time comes to sell. For the California emissions.
