2015-2016 Ford Expedition & Lincoln Navigator Get More Power With K&N Air Intake

K&N intakes are designed to reduce intake restriction as they smooth and straighten air flow

The heat shield isolates the filter from underhood heat, allowing outside air to flow to the motor

The 2015-2016 Ford Expedition and Lincoln Navigator were available with the EcoBoost V6, a sophisticated twin-turbocharged 3.5L V6 engine that features an aluminum engine block and cylinder heads, DOHC four valve per cylinder heads, direct fuel injection, direct acting camshaft tappets, and twin-independent variable cam timing (Ti-VCT). The engine produces 365 horsepower and 420 lb-ft of torque, an improvement of 55 horsepower and 55 ft-lb of torque over the 5.4L V8 engine it replaced in the Expedition and Navigator.

While all that power certainly made for an impressive 0-60 time of 6.2 seconds, it also provides for 6,600 lbs. of trailer-towing capacity.

Chevrolet continues to go down the V8 route with its successful LS series engines. Powering the competitive Chevy Tahoe SUV is the Bow Tie’s 5.3L V8, which produces 355 horsepower and 383 lb-ft of torque. Properly equipped the Tahoe has a trailer-towing capacity of 6,600 lbs., identical to the Expedition and Navigator.

The K&N Replacement Filter is engineered to fit perfectly in the original factory airbox

The intake tube is optimized to feed both turbochargers equal air flow

“Cool,” you think. “I’m all set to blow the doors off the next Tahoe I pull up next to at the traffic light.” Not so fast. Your engine is turbocharged, In fact, it has two turbochargers. And what turbochargers need to make power is air. Lots of air. And K&N can help feed your engine even more air than the factory system.

The K&N 57-2595 cold air intake is a free-flowing air induction system designed to replace the restrictive factory air filter and air intake tubing on some 2015-2016 Ford Expedition and Lincoln Navigator 3.5L models to increase performance and response.

The air intake system comes with a high-flow K&N RC-5173 air filter and an aerodynamically-engineered intake tube. The system easily connects to your vehicle’s factory engine throttle body to dramatically increase air flow into your engine. This FIPK Air Intake System accommodates the factory air temperature sensor.

The filter can be used for up to 100,000 miles before cleaning is needed (depending on conditions)

The tapered cylinder shaped K&N air filter is made from highly-effective oiled cotton fibers

K&N engineers developed the 57-2595 performance cold air intake system, which they tuned and dyno-tested to improve acceleration and throttle response. One key to the K&N 57-2595 FIPK air intake system is the oiled cotton filter media that achieves high airflow coupled with high filtration levels, protecting your engine from harmful road grit, dust, and dirt. Further, the filter is mounted right at the front of the Expedition and Navigator where it can take full advantage of the cool incoming air, protected by a proprietary heat shield to keep underhood temperatures out of the engine’s intake.

The other key is the rotationally molded tube made from interlaced high density polyethylene (HDPE). Utilizing this material permits K&N to precisely shape the tube to reduce turbulence and accelerate airflow into the engine. It also provides the ability to develop tubes with unique shapes that are specifically engineered for each application, like that of the Expedition and the Navigator.

The results are impressive. On a chassis dynamometer, a 2016 Ford Expedition recorded 268 horsepower at the wheels. A K&N 57-2595 FIPK air intake system was then fitted and the SUV retested. With only the change to the intake, horsepower had jumped to 275, an estimated increase of seven horsepower at the wheels. Similar results were measured for torque, rising from 345 ft-lb to 351 ft-lb. Plus, drivability and response have been improved.

There’s no drilling required as OEM mounting brackets are utilized for a seamless installation

Everything needed to install the 2015 - 2016 Expedition or Navigator kit is included in the box

The K&N 57-2595 FIPK air intake system comes complete with a round tapered six-inch K&N RC-5173 low restriction air filter. The K&N 57-2595 air intake systems also comes with the necessary clamps and hardware for an OEM-type appearance, using only factory holes and mounting points. Installation is a relatively straightforward process that takes no more than 90 minutes with tools just about everyone has in their garage.

The oversized air filter also captures and holds more dirt increasing the service life before a cleaning is required (up to 100,000 miles, depending on driving conditions). When it’s time to clean your filter, the K&N Recharger Kit 99-5000 has everything you’ll need. The kit comes with K&N Power Kleen air filter cleaner and K&N air filter oil. Apply K&N Power Kleen to dissolve dirt build up and old filter oil, rinse with water, dry, then apply fresh filter oil to your air filter and reinstall it.

If you consistently drive in dirty, dusty, or wet conditions, consider a K&N RC-5173DK air filter wrap, which is a silicone treated, polyester wrap that is made to cover K&N air filters and provide additional protection without impeding airflow.

The K&N 57-2595 FIPK air intake systems are CARB exempt and legal for use on the streets of all 50 US states. They also come with K&N's 10-Year/Million Mile Limited Warranty.
