More Horsepower for 2017-2018 Nissan Titan XD 5.6L Models with K&N Intakes

Engineered specifically for 2017-2018 Nissan Titan XD 5.6L V8 models, the K&N® 63-6020 air intake system provides a guaranteed increase in horsepower and torque—and features a washable, reusable High-Flow Air Filter™ to help protect against damaging engine contaminants.

If you want to give your Titan XD more power, check out the 63-6020 performance air intake system—specifically designed to fit in the engine bay of 2017-2018 3.2L V6 Titan XDs. The 63-6020 is designed to help keep engine air cooler (which can increase engine combustion efficiency), and provides a smooth, low-restriction path for airflow to the engine. Many stock intake systems have airflow-obstructing components that can create turbulence—and thus heat—resulting in less efficient combustion, and giving you less horsepower. By replacing the complete factory system with an aerodynamic tube and High-Flow Air Filter™, your engine will have access to a higher volume of cool air—giving you a guaranteed increase in horsepower and torque.

“Easy install, smoothed out the whole system. Instructions were clear and relatively simple. I had previously installed a new cat-back pipe and wasn't completely sold on the sound...the K&N intake helped the engine breathe and actually gave me a rich, deep, smooth tone from the pipes. Noticeable increase in response as well.” – Preston from Wilmington, Delaware [Part No. 63-9039]


Typical factory air intake systems force air through a restrictive disposable paper air filter before the air travels through a complex system of tubing—which often has tight bends, baffles, and other elements that can cause swirling, turbulent air. Excess turbulence can cause the molecules within the air to collide, which creates heat—and an increase in temperature reduces the density of oxygen molecules in the air. Since engine combustion is most efficient in an oxygen-rich environment, keeping engine air cooler often significantly increases engine combustion efficiency.

The 63-6020 intake system features a free-flowing, high-density polyethylene intake tube, which is engineered to reduce turbulence in the air, keeping engine air cooler—and increasing engine performance! The 63-6020 also incorporates a steel heat shield, which helps protect the air filter and intake air from high engine temperatures.

“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 Bristol, UK [Part No. 69-6000TP]


Most factory disposable paper filters only “surface load” contaminants—collecting them on the surface of the media, which over time can reduce the filter’s efficiency due to clogging. Alternatively, High-Flow Air Filters™ “depth load” contaminants; multiple layers of cotton fibers capture particles on many levels. Because the contaminants are incorporated into the filter fibers, the filter can still operate without significantly reducing its performance.

The High-Flow Air Filter™ included in the 63-6020 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. 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.

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

The K&N 63-6020 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.

“Couldn’t be happier with this intake. Easy installation, great sound and noticable performance. Looks great, sounds great and performs as advertised. Well done K&N.” – Shawn from Raleigh, NC [Part No. 69-8621TTK]


K&N performance air intake systems come with a horsepower guarantee—you will get an increase in horsepower and torque! During dynamometer testing, a stock 2018 Nissan Titan XD 5.6L with a factory air intake system was recorded at 317.1-horsepower at 5,502 RPM. After installation of 63-6020, the same vehicle was recorded at 327.0-horsepower at 5,502 RPM—an estimated increase of 9.9-horsepower. The torque also jumped from 250.5 lb.-ft. to 267.2 lb.-ft.—an estimated increase of 16.7 lb.-ft. at 3,024 RPM.

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. Please visit individual product pages to view horsepower estimates for your specific vehicle.

“Everything that was needed was included in the box. The install was easy, under one hour. It took longer to put the air box together. The engine sounds great and pick up has improved. I am very satisfied with this system. It does make a big difference in driving and puts a big smile on your face.” – G MAN from Mesa, AZ [Part No. 63-1561]


For many vehicle applications, multiple options of K&N intake systems are available. 69-Series and 77-Series intakes feature mandrel-bent aluminum intake tubes, while 57-Series and 63-Series intakes have high-density polyethylene intake tubes. 71-Series intakes are from the Blackhawk Induction™ line, which feature a black powder-coated aluminum intake tube and a black oil-free synthetic filter. Please view the specific product pages for details on each intake type.
