    Features & Details

    • Increases Airflow for Better Performance
    • Improves Throttle Response and Fuel Mileage
    • Reusable High Flow Air Filter
    • NO Computer Tune Required
    • Simple Bolt-On Installation
    • CARB EO# D-418-14
    • Fits All 2004-2006 4.6L F-150s
    Superior Intake Flow from a Bolt-On Part. Send 400 cubic feet per minute of cold air streaming into your 2004-2006 F-150’s 4.6L engine like an oxygenated gale with the Roush Cold Air Intake, a bolt-on component that gives your truck an instant power upgrade. This leads to approximate maximum gains of +10 horsepower and similar amounts of torque, along with real, dyno proven torque and hp gains over the whole RPM band. While you’re enjoying the added power alongside better throttle response and boosted fuel mileage, you'll also savor a stronger induction sound coming from under the hood.

    No Additional Tuning Needed. The Roush Cold Air Intake, in this variant at least, is designed to be transparent to the stock tune. No aftermarket tune is needed to get it up and functional at its peak effectiveness, and you can leave the OE tune in place if you wish without any detriment to the new component.

    A Filter You Can Reuse for Years. The Roush Cold Air Intake features an advanced filtration element that has a nanofiber filter, rather than one made of cotton gauze – which ups interception of 0.5 micron particles by 600% and 2 micron particles by 200%. The filter is reinforced with an inner and outer layer of wire mesh and is 100% washable and reusable to spare you future expense.

    Made for a Good Fit. In addition to its cutting edge nanofiber filter, the Roush Cold Air Intake features other ultramodern materials and construction techniques to increase its durability. The component features a tough sheet steel heat shield with a black textured powder-coat finish to deter rust, plus an EPDM foam seal at the top to create a bond with underside of the hood. The intake tube is cross-linked high-density polyethylene, also black and with a textured surface to match the heat shield. It is USA-made.

    OE Sized MAF Housing. The MAF housing of the Roush Cold Air Intake is designed to fit the stock MAF (85mm). The tubing also includes other necessary attachment points for sensors, hoses, etc.

    Bolts Into the Engine Fast. The Roush Cold Air Intake bolts on directly to your F-150’s engine in the space formerly occupied by the stock intake. Once that is removed, the new CAI attaches to the same mounting points, using the included instructions and hardware pack.

    Warranted for 90 Days plus a Lifetime Filter Warranty. The Roush Cold Air Intake is covered by a standard 90 day warranty against defects from the manufacturer. However, the filter element itself is covered by a separate limited lifetime manufacturer's warranty.

    Has a CARB Executive Order #. Possessing the CARB EO Number #D-418-14, the Roush Cold Air Intake is made to be CARB exempt and is legal for street driving in all 50 states of the USA. The component can be bought and installed anywhere in America, and is suitable for both on-road and off-road use. When installed, you should take care to place the CARB sticker in a visible location so that your vehicle will pass inspection, assuming you live in California or another CARB area.

    Application. This Roush Performance Cold Air Intake Kit is specifically designed to fit the 2004-2006 F-150s equipped with the 4.6L V8 engine.

        How much horsepwer am I looking at paired with a 75mm BBK throttle body, i already have my truck tuned with the SCT X4 and full Magnaflow duals no cats

        • The Roush Cold Air Intake paired with a BBK 75mm Throttle Body should net approximately 15-20hp.

        Why is this item described as a CAI when it's under the hood of a HOT engine? To be a CAI, it is proven this item would have to extend at least 3 feet IN FRONT of the vehicle thus producing 7-8 HP increase on a Dyno.

        • This is described as a cold air intake due to it being a cold air intake as it will still bring cooler air into the engine producing HP.

        I have a 2004 F-150 4.6L 2V STX SuperCab. Is this compatible with the 2V 4.6L, and if not. Why isn't it compatible? Also, will it work with BBK's 75mm Throttle Body?

        • This is compatible with the BBK 75mm throttle body as well as being compatible with the 2V 4.6L 2004 F-150 STX SuperCab's.

        I am curious as to why this Roush CAI features a different heat shield than the product listed for this truck on the Roush website? Also wondering if there are any other differences? ex: filter size, material, tube size etc thanx

        • The cold air intake on our website and Roush's are exactly the same. The heat shield may be the only difference. The filter as well as the tubing are identical.

            As expected

            Instructions are a bit cumbersome, but the final result is worth it. Sounds clean and real good. Recommend
