The Mercury Grand Marquis Air Duct supplies your engine with measured airflow directly from the filter box to the intake manifold. The tough molded body minimizes any heat and vibration effect that might cause cracks that would permit bypass flow of dust. As the Air Duct sits ahead of the mass air flow sensor, it ensures accurate fuel metering, which protects Mercury engines from damage caused by lean mixes and allows every Grand Marquis to start off smoothly and pull confidently on the highways. Owners praise the component for retaining the original equipment manufacturer mileage and emissions figures, thereby keeping maintenance costs low. The part fits any sedan or wagon produced over four generations, so whether your Grand Marquis came off the line in 1979 or 2011, stock clips and grommets align and lock in the Air Duct installation in minutes. Configuration allows fans to restore ruggedness without modifying the Mercury airflow geometry or cabin quietness. By directing thousands of gallons of oxygen every hour, the Air Duct silently contributes to engine durability, backing up the generous V8 torque that made the Grand Marquis a reliable long-distance traveler. Safety also increases because a sealed Mercury intake path prevents the occurrence of sudden stalls during emergency stops or sharp turns. Many Grand Marquis fans swear by this Mercury specific Air Duct due to its long-lasting performance. The Air Duct's heat-insulated ribs absorb engine movement while its flexible joints allow easy installation. Its smooth inner surface provides a lower turbulence air inflow. The OEM Air Duct provides the desired Mercury feel of throttle response and allows for faithful idling and acceleration of the Grand Marquis just like it was meant to.
