High Inflow CAI for More Power.
Your 1997-2003 F-150’s 5.4L engine runs mainly on two things – fuel and air – and the Injen Power-Flow Polished Cold Air Intake creates an energizing increase to airflow that helps transform your truck into a champion. Doing away with the stifling restrictions of the stock intake, the Power-Flow CAI combines a high-flow fabric filter, wide-open intake tubing, and an extra-large filter element to supply +10 horsepower and +11 ft-lbs of torque to the typical pickup. You’ll also get some extra fuel savings, too, with gains of +1-2 mpg in gas mileage likely!
No Additional Tune Needed.
The Injen Power-Flow Polished Cold Air Intake works just fine with your truck’s stock tune – there’s no need to flash the engine with an aftermarket tune to win the power and performance gains this CAI offers. At the same time, its engineering is flexible enough so it’ll still function correctly if you do choose to tune the ECU for other purposes. You can count on this Injen component with either a tuned or untuned engine.
Reusable Dry Filter with High Flow Capability.
Unlike the paper used for the stock air filter, the Injen Power-Flow Cold Air Intake’s filter element is made from non-woven nanofiber material that doesn’t block airflow. Washable and reusable, the blue filter is also dry, so you’re spared the trouble of re-oiling it before reinstalling it after a cleaning. Replacement filters are also readily available from Injen.
Rust-Proof Aluminum Construction.
Using the same grade of aluminum that’s utilized for aircraft and marine parts, the Injen Power-Flow Polished Cold Air Intake features a 6061 aluminum intake tube. This tube is highly polished to give a silver accent to your truck’s engine. A black textured heat shield is also included to block engine heat. The filter element is made from nanofiber, which admits plenty of air while removing harmful particles. This component is 100% USA-made with pride.
Includes Special MAF Housing.
The Injen Power-Flow Polished Cold Air Intake is engineered with a housing to accommodate the MAF. This section includes a “stepped down” intake pipe diameter change to tune the intake for use with a standard MAF.
Handy to Install.
This short ram air intake is supplied with hardware and CNC-machined stainless steel clamps for fitment. Bolting onto the same mounting points as the stock intake, the Injen Power-Flow Polished Cold Air Intake attaches with basic automotive hand tools, with drill-free and cutting-free installation.
Lifetime Manufacturer’s Warranty.
Made to high quality standards in America, the Injen Power-Flow Series Polished Cold Air Intake is covered by a limited lifetime manufacturer’s warranty.
