When Ford engineers started working on the fourth generation Ford Super Duty back in 2012, there was a lot at stake. General Motors and Dodge had already stepped up their heavy-duty truck game, so Ford needed to redefine the segment. The original Ford F-250 and F-350 Super Duty were known for their prodigious capabilities, comfort, and style. In order for the new one to break new ground, they used an all-aluminum body so that the weight savings would negate the heft of a fully boxed high-strength steel frame. To simplify future repairs, the cab and many of the interior components were shared with the Ford F-150. Then loads of luxury amenities were added to the options list, like a panoramic roof, massaging seats, multiple exterior cameras, and a trick new variable-ratio steering system that combined the reliability of hydraulic steering, with a steering wheel mounted electric motor to reduce the steering input required at low speeds. Under the hood, the 2017 Ford F-250, 2017 Ford F-350, and 2017 Ford F-450 get a revised version of the 6.7L Powerstroke diesel V8. A larger turbo, new injectors, and a more powerful fuel pump increased the torque from 860 lb-ft to 925 lb-ft, making the Ford Super Duty one of the quickest and most capable heavy-duty trucks on the market. But even Ford’s new trucking perfection can be improved on when you add an estimated increase of 11 horsepower and 23 lb-ft of torque.

Diesel engines, like the Powerstroke in the 2017 Ford F-250/F-350/F-450, creates power by compressing a mixture of fuel and oxygen until it explodes. To intensify the horsepower and torque output, more oxygen-rich air is injected into the cylinders via a turbocharger. In the case of the 6.7L Powerstroke, a massive Garrett turbo is nestled in the ‘V’ of the motor, where the exhaust gases can more quickly spool up the turbo’s air compressor and pump air into the engine. The air that it compresses, comes from the stock Ford Super Duty air intake, which has to pull in outside air through some rather restrictive components. For example, the OE air box can only ingest air through a small opening in the bottom, and the ‘surface loading’ paper air filter can actually block airflow as the miles increase and the filter gets dirty. A K&N 63-2597 AirCharger performance intake on the other hand, virtually eliminates these airflow restrictions, so your big Ford can work much more efficiently. Here’s how it works:

Getting Air In

In place of the factory 6.7L Powerstroke air box is an oversized K&N high-flow performance air filter, surrounded by a self-sealing heat shield. When the hood is closed, a specially designed gasket on top of the heat shield prevents warm engine air from being drawn into the intake. This allows the low restriction K&N air filter to take in a high volume of cold outside air. Its proprietary cotton gauze material is then able to remove up 97% of the airborne contaminants, thanks in large part to a unique oil treatment that causes the cotton fibers to become sticky and hold onto the dirt for up to 100,000 miles (depending on road conditions).

Getting Air to the Motor

Once the air has been cleaned, it travels to your 2017 Ford Powerstroke through a wide diameter intake tube. The narrow OE intake is made from corrugated plastic, which can cause the air to become turbulent and heat up. When this happens, the heat buildup reduces the oxygen content and can ultimately reduce the amount of power the engine makes. To reduce air turbulence, the K&N 63-2597 AirCharger performance intake utilizes a roto-molded intake tube that's been aerodynamically designed to provide a direct path to the compressor. This keeps the air temperature low, that way the oxygen content remains high. And there's even an integrated fitting for the factory mass airflow sensor, so the system can be installed without reprogramming the ECU.

To most people, the most important benefit of installing a K&N 63-2597 cold air intake would be getting an estimated increase of 11.4 horsepower & 23.01 lb-ft of torque. But that's only part of the story. You see, the additional air that it provides helps your turbo to spool up faster so that 6.7L Powerstroke can deliver power lower in the rev band. This can also reduce engine strain and allows the throttle to respond much faster to your inputs. You're also going to save money, because that K&N performance air filter is reusable, and it's backed by the K&N 10-Year/Million Mile Limited Warranty.

The K&N 63-2597 is designed to fit the following vehicles:

2017 FORD F450 SUPER DUTY 6.7L V8 Diesel Engine - All Models
2017 FORD F350 SUPER DUTY 6.7L V8 Diesel Engine - All Models
