Gen. 3 specific camshafts, enlarged intake and exhaust valves, an increased compression ratio of 12.0:1, a revised intake manifold, and 7500 RPM redline in the Mustang. With these changes the updated 5.0L Coyote is rated by Ford at and . Boss 302 (Road Runner) Variant A higher performance variant of the Coyote, dubbed Road Runner internally by Ford, is produced under the Boss 302 moniker used for the resurrected Boss 302 Mustang for the 2012 model year. The Boss 302 receives CNC ported heads cast in 356 aluminum providing additional airflow and strength, and a higher lift exhaust camshaft profile is used. Valvetrain components were lightened as much as possible, including the use of sodium filled exhaust valves, while strengthened powdered metal rods and forged aluminum pistons were added. Piston-cooling jets were also deleted, which are standard in the 5.0 model. Exterior changes include a high-mount intake plenum (as opposed to the standard engine's low-mounted one) with shorter runners to improve high-rpm power. Power is increased from to , and torque drops from to due to the upgrades. The Boss's redline is increased to 7500 rpm, but has been verified stable up to 8400. F-150 variant A torque-biased variant of the Coyote is produced as an alternative to the EcoBoost V6 in the F-150 pickup truck. The F-150 5.0L receives a lower compression ratio (10.5:1), intake camshafts with less duration, cast iron exhaust manifolds, and revised cylinder heads to improve cooling. The intake manifold changed only in color, and height. These changes promote low-end and mid-range power and torque. The engine retains the Coyote's forged steel crank and piston-cooling jets but benefits from the addition of an external engine oil cooler similar to the Boss 302's. The changes result in the engine's peak horsepower dropping to at 5500 rpm, while torque is rated at at 4250 rpm. When the 2015 F-150 was revealed, Ford improved the induction system to pull air from above the grille under the hood (aka Ram Air Effect) as opposed to the fender intake inlet that had been used for all previous Ford Modular Engines. The addition of Ram Air Effect pulled more cool air into the engine in favor for a power increase to at 5750 rpm and at 3850 rpm. For 2018, numerous revisions were made to the 5.0. Most notably, the adoption of a port and direct fuel injection system, as well as
