Guaranteed Horsepower and Torque for 2019 Ford Mustang GT 5.0L V8

The 63-2605 after installation

The Ford Mustang has long been known as one of America’s favorite muscle cars—and now you can pair your 2019 Ford Mustang GT with an industry-leading air management system from K&N. Help protect your engine and gain a guaranteed increase in horsepower and torque with the K&N® 63-2605 air intake system, engineered specifically for 2019 Ford Mustang GT V8 models. The K&N® 63-2605 roto-molded air box intake system boasts an estimated power increase of 22.1-horsepower and 13.8 lb./ft. of torque*, and up to 31% more airflow than the factory intake system.

CAD-designed in order to help ensure a precise fit, the 63-2605 is engineered to effectively utilize space in the engine bay and reduce airflow restriction. An 8-inch conical filter with 600 square-inches of filter media helps ensure exceptional airflow and contaminant capture, and a 19 square-inch opening is precisely placed to utilize the vehicle’s stock source of cool air.

The 63-2605 is designed to help keep engine air cooler, which can increase engine combustion efficiency, and helps provide a smooth, low-restriction path for airflow to the engine. Your engine needs oxygen to create power; the cylinders in your vehicle’s engine have to have air to create the explosion that produces horsepower and torque. Since cold air contains more oxygen molecules than warm air, injecting a higher volume of oxygen-rich air into the cylinders allows the engine to burn fuel more efficiently during combustion—providing an increase in power.

In a typical stock air intake system, air has to pass through a thick, disposable paper filter, and then move through a narrow system of tubing that can cause air to swirl and become turbulent. Excess turbulence causes the molecules within the air to collide, creating heat, which lowers the density of the air and reduces the efficiency of combustion. All K&N intake systems are specifically engineered to help keep your engine air cooler.

“I definitely can tell the difference in performance, extremely happy with the results.” – J from California [Part No. 77-1560KTK]

Since engine combustion is most efficient in an oxygen-rich environment, keeping engine air cooler often significantly increases engine combustion efficiency. The 63-2605 intake system features a free-flowing, high-density polyethylene intake tube, which is engineered to reduce turbulence in the air, which helps keep engine air cooler and increases engine performance! The 63-2605 also incorporates a roto-molded air box design, which helps protect the air filter and intake air from high temperatures within the engine bay.

“Great product, easy to install (1h in my case). You can feel the difference on acceleration and the sound is just great.” – Maxime from Canada [Part No. 69-1211TTK]

Under normal circumstances, most automotive air filters demonstrate an inverse relationship between airflow and efficiency—the higher the airflow, the less efficient the air filter is at protecting the engine, and vice versa. The oiled design of K&N air filters assists in “absorbing” dirt particles—and in turn helps incorporate those particles into the filter surface itself, which helps maintain the filter’s efficiency and ability to flow air. When tiny particles are captured and saturated with oil, they in turn can become tacky, allowing them to capture other particles.

The High-Flow Air Filter™ included in the 63-2605 intake kit is oversized with a conical shape, providing a greater surface area and allowing for a service interval of up to 100,000 miles between cleanings (under normal highway driving conditions). High-Flow Air Filters feature an oiled, layered design—providing up to 50% more airflow than a traditional paper filter. When your filter does need to be cleaned, you can use the K&N Recharger® Kit (99-5000 or 99-5050) to quickly and easily restore your filter’s performance. Each K&N intake (and filter!) is designed to last for the life of your vehicle.

“Amazing product, sounds great and would recommend to anyone. Very prominent when accelerating and in the higher rev range. This is my first K&N product and would definitely buy from them again.” – Zachary from the United Kingdom [Part No. 69-6000TP]


The K&N 63-2605 intake system is engineered to incorporate factory mounting points and the factory mass air sensor. Installation can typically be completed in 90 minutes or less, and requires only simple hand tools. Detailed instructions are included in your kit, and installation videos for many vehicles are available on the K&N website.

Each intake system comes with a 10-Year/Million Mile Limited Warranty. Furthermore, using a K&N replacement air intake system will not void your factory warranty; in the U.S., manufacturers must provide evidence that an aftermarket part is the cause of a necessary repair in order to void or deny warranty coverage. The Consumer Products Warranty Act of 1975 (also known as the Magnuson-Moss Warranty Act) protects consumers’ rights to their warranty coverage.

“Great product. Easy to install. And wow what a performance improvement.” – Marcus from North Carolina [Part No. 71-4519]


K&N performance air intake systems come with a horsepower guarantee—you will get an increase in horsepower and torque! During dynamometer testing, the 63-2605 provided a power increase of approximately 22.1-horsepower and 13.8 lb./ft. of torque* over the stock system.

“Easy install that anyone can do. Sounds great and the performance has noticeably improved.” – Anthony from New Jersey [Part No. 69-9508T]
