Product Description

The K&N 77-2570KTK 77 Series High-Flow Performance Air Intake System delivers a guaranteed increase in horsepower and torque for 1997-2016 Ford E-Series vans equipped with 5.4L V8 or 6.8L V10 engines. This complete intake system replaces the restrictive factory air box and intake tube with a free-flowing mandrel-bent aluminum tube and oversized high-flow air filter. K&N dyno testing confirms gains of 17.48 HP at 4101 RPM and 22.4 lb-ft of torque. The textured black powder-coated intake tube accommodates the factory mass air sensor and air temperature sensor for seamless integration. A custom heat shield installs in the factory air box location and connects to the original fresh air scoop, protecting the intake from engine bay heat. The chrome-topped conical filter features K&N's legendary oiled cotton gauze media, providing exceptional filtration while dramatically improving airflow. Installation typically completes in 90 minutes or less using basic hand tools. Ideal for commercial vans, shuttle buses, and motorhome/RV applications where improved throttle response and towing performance are essential. Backed by K&N's 10-Year/Million Mile Limited Warranty.
