The K&N 63-6019 Air Intake fits some Nissan Titan models. See vehicle applications link for details.
The 63-6019 Aircharger Intake System was designed to fit specific Nissan Titan models. K&N Aircharger air intake systems are designed to dramatically reduce intake air restriction and increase air flow. More air means more usable power and acceleration throughout the engine's RPM range. This Aircharger Intake System begins with a cone-shaped K&N high-flow air filter which is made from an oiled cotton-gauze media. This filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. Air funnels through the velocity stack then through the aerodynamically designed K&N tube which connects to the throttle body. A rubber-lined heat shield is installed between the intake tube and air filter using the factory mounting locations to keep out hot engine bay temperatures. Additionally, the factory mass air flow sensor and both EVAP hoses mount directly on the intake tube. This design allows cooler, denser air in to the engine guaranteeing power gains compared to the factory system. When you put a K&N Aircharger Air Intake System to work, you can feel confident that you've got a product specially designed and tested for your specific engine demands. This air intake cannot be sold in California. It is not legal for use in California or other states adopting California emission standards.

K&N 63-6019 Air Intake Product Reviews

Friday, February 23, 2018 - Part 63-6019
This is my first K&N intake and I am generally pleased with the performance increase, but I will say the quality of the components (minus the filter) are not as refined as competitor products I have used. Whether that will effect its durability in the long run is yet to be seen. During install I also had to remove the small air duct in order to install the filter, which was not listed in the instructions.

Just order it if you want your truck to sound like a real man's truck.

Easy to install and fit as advertised. Noticed a smoother idle and a deeper sound from the engine. Due to the way the transmission shifts not a huge difference in power. The fuel mileage has increased about 3/4 of a mile per gallon. Used the Nissan Consult, Nissans scan tool and monitored the before and after readings at the MAF. There was a noticeable difference in air flow at idle to about 4500 RPM after that a slight difference in flow. Happy with the product. It does what it says it will do.

This thing is AWESOME! Completely brought my 2017 Pro-4X to life. THIS is how the truck was supposed to run from the get go, night and day difference. I promise you will not be disappointed by installing this cold air intake in your 2017 Nissan Titan. Installed in approx. 1 hour by taking my time, but could probably do it much quicker now. Five stars

WOW... Just WOW! My truck accelerates so much smoother, the low end throttle response is excellent. I also have a Magnaflow 22 muffler, and now with the K&N CAI, it sounds amazing!

Installed on a 2017 Nissan Titan 5.6l V8 (non XD). Installation was easy. Fits perfectly. Definitely feel better throttle response. Running it with stock exhaust but sound signature definitely improved when accelerating (above 3500 rpm). Sounds much more throaty. When cruising I hear no difference which is good. Absolutely no hissing sound. And to top it off, I experience a 1.5 MPG improvement in my consumption. The CAI will pay itself off in no time. Very happy.
