Visually Handsome CAI with Real Performance Gains.
Designed to get your 2004-2008 V8 F-150’s 5.4L engine roaring with fresh power and dynamism, the Injen Polished Power-Flow Cold Air Intake also adds a liquid gleam of mirror-polished metal to your engine compartment for a bit more pizzazz. This short ram intake is built for plenty of capacity, with a large diameter intake tube and a beefy filter to handle a strong inflow. The cool air sucked in through this setup generates up to +10 horsepower and +11 ft-lbs of torque, helping to turn your F-150 into a hard-charging powerhouse.
No Need for Engine Tuning.
Engineered to step down the intake diameter at the point where it passes the MAF, the Injen Power-Flow Cold Air Intake effectively comes “pre-tuned” to automatically give your F-150’s engine superior performance. There’s no need for a separate engine tune to get the part working correctly with your system – the Injen CAI functions flawlessly with a stock/factory tune. If you decide to add an aftermarket tune to refine your pickup’s performance, the intake will continue to work just as well.
Dry Reusable Air Filter.
The blue air filter element in the Injen Polished Power-Flow Cold Air Intake is dry and needs no oil to function, so you needn’t worry about re-oiling when cleaning it later. The material it’s made from is nano-fiber, filtering out lots of different contaminants while enabling high air flow. The filter can be washed and reused repeatedly for some welcome savings over time.
USA-Made with Precision.
The Injen Polished Power-Flow Cold Air Intake is 100% USA-made, using topnotch materials such as the 6061 aircraft grade aluminum the intake tube’s fabricated from. The highly polished finish makes this something of an “engine dress-up part” as well as a practical addition to your truck’s performance. The filter is protected from the engine’s heat with a heat shield, and is made from advanced nanofiber material. The parts are CAD designed, and, where appropriate, CNC-machined for an exact fit.
Houses the OE MAF.
The Injen Polished Power-Flow Cold Air Intake is constructed with a mounting area sized to accommodate the stock MAF sensor. The tubing size is “tuned” to ensure the MAF functions properly with this intake.
Bolt-On Direct Replacement.
The Injen Power-Flow Cold Air Intake is packaged with all the stainless steel clamps and high grade hardware needed to install it. You can bolt it on in place of the existing intake without the need for drilling or other modifications.
Lifetime Warranty Coverage.
Injen protects the Polished Power-Flow Cold Air Intake with a limited lifetime manufacturer’s warranty.
Not Street-Legal in CARB States.
The Injen Power-Flow Cold Air Intake is not street-legal in states like California where CARB regulations apply, since it doesn't meet CARB compliance standards. The intake is 49-state legal only.
This Injen Power-Flow Series Polished Cold Air Intake is designed to fit the 2004-2008 F-150s equipped with the 5.4L V8 engine. Technical Note. This Injen Cold Air Intake is not legal for use in California or other states adopting California emission standards.
