2010-2014 Ford Mustang Shelby GT500 Get Estimated 30 More Street Legal Horsepower
- 4 Sept 2015
The Ford Mustang Shelby GT 500 moniker dates back to 1967 when the legendary Ford Pony Car received its first significant styling and mechanical changes. The Mustang Shelby GT 500 followed in the footsteps of the earlier 289 cubic-inch “HiPO” V8 powered and Shelby modified GT 350. Changes made to the first generation Mustang suspension and engine bay for the 1967 model year allowed Ford to stuff a 390 cu-in Ford big block FE motor under the hood. Not to be outdone, Carroll Shelby upped the ante by inserting a 428 cubic-inch police interceptor engine fueled by dual 4-barrel carbs into the new for ’67 Ford Mustang Shelby GT 500. At the time the 390 V8 was the biggest engine available off the Ford production line, so the 428 powered GT 500 was truly a rare specimen.
Forty years later Ford revived the legendary Shelby GT 500 marque with a modern take on styling, handling, and performance. Of course horsepower and engine displacement were higher than any other Mustang GT of the time. The 2007 Ford Mustang Shelby GT500 was powered by a supercharged 5.4L modular V8 mated to a 6-speed Tremec TR-6060 manual transmission. The 2007 Shelby GT500 Mustang was rated at 500 horsepower, and by 2014 when the GT 500 went back into hibernation power output was raised to an incredible 662 horsepower from a supercharged 5.8L V8.
While the 2010, 2011, 2012, 2013 and 2014 Ford Mustang Shelby GT 500 models are some of, if not the, most powerful factory production Mustangs ever, owners of these cars can easily bolt on more horsepower with a K&N intake system that is legal in all 50 states. The concept behind a K&N air intake system is simple. In the case of a 2010-2014 Mustang GT 500, K&N air intake 57-2579 replaces restrictive factory induction components with a free-flowing roto-molded black HDPE air intake tube coupled to a high-flow K&N air filter allowing the supercharged engine to breathe easier. A combination of reduced intake tract restriction, straighter airflow, and an application specific air filter heat shield add up to massive gains in street-legal horsepower and torque for 2010-2014 Ford Mustang Shelby GT 500 models.
After establishing baseline power readings, the K&N 2010-2014 Shelby GT500 intake, number 57-2579, was installed on an otherwise stock 2011 Ford Mustang Shelby GT 500 5.4L supercharged engine and dyno tested in-house by K&N filters. The results were an astounding estimated additional 30.49 street-legal horsepower and 30.95 lb-ft of torque at the rear wheels of an already outrageous car. Similar, or perhaps better, results can be expected from 2013-2014 Ford Mustang Shelby GT 500 models powered by the larger 5.8-liter V8. No additional modifications or tuning are required to experience an increase in power from K&N air intake 57-2579. K&N backs its 2010, 2011, 2012, 2013 and 2014 Ford Mustang Shelby GT 500 air intake with a 10-year/million mile limited warranty. Significant testing goes into developing a K&N air intake system, so for those 2010-2014 Shelby GT500 owners looking to the step up to the next level of performance or just wow their friends, look no further than the K&N 57-2579 FIPK air intake system. K&N air intake, number 57-2579, is designed to provide a guaranteed increase in performance that is street legal in all 50 U.S. states for the following Ford Mustang Shelby GT500 models: 2014 Ford Mustang Shelby GT500 5.8L V8 Use the K&N Dealer Search to find an authorized K&N retailer or installer in almost any part of the world.
