More Horsepower and Torque for 2015-2017 Ford Mustang 3.7Ls

2017 Ford Mustang

K&N® has just released a new 50-State legal intake option engineered specifically for 2015-2017 Ford Mustang 3.7L models. The K&N® 57-2594 high-density polyethylene (HDPE) intake system offers an estimated power increase of 7.49-horsepower and 7.72 lb./ft. of torque*, exceptional engine protection, and improved engine sound on acceleration.

“Very pleased with my new K&N intake! Gave my Mustang the sound I was looking for and it looks great. Easy to install and shipping was fast. Highly recommended!!” – William from Wisconsin [Part No. 63-2578]


The 57-2594 is designed to help 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 need to have air to create the explosion that produces horsepower and torque. Allowing a higher volume of air into the cylinders allows the engine to burn fuel more efficiently during combustion—providing an increase in power.

“I was very impressed with the ease of ordering on the website and how fast my item was shipped. My Performance Intake Kit has added so much horsepower to my 2013 Mustang Gt and I am so happy with my purchase, I did not think it would make such a difference but it really made my car that much faster.” – Dawn from Michigan [Part No. 63-2578]

57-2594 K&N cold air intake system


The 57-2594 intake system features a free-flowing, high-density polyethylene intake tube, which is engineered to provide a smooth path for airflow and a higher volume of air to the engine. The 57-2594 also incorporates a steel heat shield, which helps protect the air filter and intake air from high temperatures within the engine bay.

“This intake is great! You definitely notice a difference from the factory to the K&N Cold Air intake also you get a more aggressive sound when you put your foot into the accelerator.” – Reed from Arizona [Part No. 69-3527TP]


High-density polyethylene (HDPE) has a very high strength-to-density ratio, as well as the ability to withstand extremely high temperatures—making it an excellent choice for the environment in the engine bay. HDPE can also be molded into custom shapes, allowing it to be adapted for specialized tubing designs.


Factory intake systems often feature intake tubing with tight bends, baffles, and other obstacles that can slow airflow and muffle engine noise. K&N intake systems are designed to give your engine a more satisfying growl on acceleration, but return to quiet once at speed.


The High-Flow Air Filter™ included in the 57-2594 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.

57-2594 cold air intake system


The K&N 57-2594 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.

Engineered to fit:

  • 2017 Ford Mustang 3.7L, All Models
  • 2016 Ford Mustang 3.7L, All Models
  • 2015 Ford Mustang 3.7L, All Models


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.

“It also gets rid of that tooty frooty sound tube. I can hear the exhaust a little better without the interference of the sound tube noise. Also, I do not want to put a tune on my motor, unlike some other cold air intakes, this intake will work without a tune.” – Henry from Illinois [Part No. 69-3527TP]


K&N performance air intake systems come with a horsepower guarantee. During dynamometer testing, the 57-2594 provided an estimated power increase of 7.49-horsepower and 7.72 lb./ft. of torque*.

*Horsepower gains vary among products and applications, but each K&N performance air intake system is designed to increase airflow efficiency for specific vehicles and their engines. Each kit undergoes significant testing to help ensure that the filter and intake tube are engineered to deliver large increases in airflow and horsepower.
