Scott Drake's reproduction of the extremely rare 1967 Mustang 390 GT High-Performance Air Cleaner without the Emissions Control Tube is a Concours Reproduction that includes a blue base and chrome lid. This air cleaner is an excellent stock appearing performance upgrade for the very restrictive 1968-70 390-428 Air Cleaners. Some early production 1968 390 GT's may have come factory with this air cleaner. For California, Emissions see part C7ZZ-9600-E.
