K&N 57-2581 50-State Legal Air Intake for 2011-2014 Ford F150 5.0L V8
CARB EO Number: D-269-48
For the American muscle car enthusiast, the term “5-oh” recalls mental images of Fox Body Ford Mustangs produced by Ford from 1978 to 1993. While a 5.0-liter displacement V8 engine was found in several GM cars during that same era, Ford practically owns the rights to using 5.0 on the side of its vehicles. As a corporate engine the 302 cubic inch (5.0L) Windsor V8 also found its way into the best-selling Ford F150 pickup. As the saying goes, all good things must come to an end and the “5-oh” Windsor block was phased out in favor of the 4.6L Modular Ford V8. Yet another saying goes something like, “what goes around comes around.” For the 2011 model year Ford brought back the 5.0-liter V8 engine. This new Coyote V8 motor was highly advertised in the Ford Mustang, but managed to find its way into the Ford F150 despite Ford’s focus on the 3.5L Ecoboost V6.
The 2011-2014 5.0L V8 equipped Ford F150 doesn’t benefit from the same level of performance as the Ford Mustang, however, it can still hold its own. Tuned for high-torque output, the F150 Coyote motor is designed to be a tough and dependable work horse. Of course, there is never any harm in increasing performance. Whether needed for towing, hauling a heavy load, or simply passing a slow moving truck, the K&N street legal air intake system for 2011-2014 Ford F150 5.0L V8 models will provide owners with superior airflow and superior performance. K&N air intake 57-2581 replaces the restrictive factory induction components found on 2011-2014 Ford F150 5.0L V8 pickups with a free-flowing roto-molded black HDPE air intake tube coupled to a high-flow K&N air filter.
This combination of increased airflow, reduced restriction, less turbulence, and an application specific air filter heat shield allows the F150 V8 engine to breathe easier. Reducing the amount of effort needed to breathe, while also increasing airflow, adds up to impressive gains in street-legal horsepower and torque for 2011, 2012, 2013, and 2014 Ford F150 5.0L V8 pickups. K&N street legal intake 57-2581 was installed on an otherwise stock 2011 Ford F150 5.0L V8 and dyno tested in-house by K&N filters. The result was an estimated additional 12.05 street-legal horsepower and 12.76 lb-ft of torque at the rear wheels of an already built Ford tough pickup. No additional modifications or tuning are required to experience an increase in power from K&N 50-state legal air intake 57-2581.
Besides increasing performance, a K&N air intake system can help Ford F150 owners spend less time and money on routine maintenance. K&N 50-state legal intake system 57-2581 includes a washable / reusable K&N high-flow air filter. The pleated cotton design, and large size allows this air filter to go up to 100,000 miles between cleanings. When it becomes time to clean the air filter, using a K&N Recharger® air filter service kit will make it function virtually like new. The durable made in the USA construction of RC-5173 means it will likely be the last air filter your 2011-2014 Ford F150 5.0 V8 will need. K&N backs its high-flow air filters, and performance air intake systems with a 10-year/million mile limited warranty to give K&N users peace of mind.
