The K&N 57-2549 FIPK air intake system replaces the restrictive factory air filter and air intake housing in some Ford F150 models. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your F150’s engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine’s RPM range. The 57-2549 air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs into the previous air box space. Air is directed through an aerodynamically engineered intake tube into the engine’s throttle body for a guaranteed power gain. The tube accommodates the factory mass air sensor, idle air and crank case vent lines. The oversized cone shaped air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install usually in 90 minutes or less using the existing factory mounting points. The tools needed are a screw driver, ratchet set and several wrench. K&N 57 Series FIPK's are street legal in all 50 US states and come with K&N's Million Mile Limited Warranty.

Have not had time to put it on

Instructions clear and good. But the nipple that screws into the air intake would not fit, called your help line they sent replacement part. No luck same fitting. Seems that air intake tube was manufactured with incorrect thread. $25.00 and a new thread chaser ( 1 time use ) problem fixed. Might be a good idea to check remaining stock. I realize that there are not many 2004 Ford Lightnings left to equip. Performance benifited. Gas mileage I don't know. When you mash the skinny peddle to much it doesnt help. Truck is one of the last one hundred made and I am trying to wear it out odometer shows 8500 mi. Overall I am quite happy with your products I also have your intakes on My 04 Expedition and 04 F250 6.0.
