The K&N 57-2568 FIPK air intake system replaces the restrictive factory air filter and air intake housing in some Ford Expedition models. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your 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 57-2568 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, brake booster vent line and a replacement silicone crank case vent hose. 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 existing factory mounting points. The tools needed are a screwdriver, ratchet set and several wrenches. K&N 57 Series FIPK's are street legal in all 50 US states and come with K&N's Million Mile Limited Warranty.

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.

I bought my first K&N air filter in January 2011 after reading all the positive reviews and am another happy customer!  I have a 2008 Ford Expedition Eddie Bauer model with 5.4L V8 engine purchased new in October 2008. I keep gas mileage records and averaged 12.8 mpg per my calculations with mostly city driving through December 2010, while the vehicle information system reported just over 13 mpg.  Since I installed the K&N filter in January with about 22,000 miles on the Expedition, I've averaged 13.5 mpg with no other work done to the vehicle. The vehicle information system reports the mpg is over 14 since I reset it right after the filter installation.  Installation was simple and a perfect fit. While I was happy with the quality permanent filter, the improved gas mileage was a nice and unexpected benefit.  Thanks K&N!

I really like the performance that I get with the K&N Filters.
They are really long-lasting with a minimum of maintenance.
Of my two most recent filters they are both over 5 years old.
My two vehicles are a 1994 Pontiac Firehawk, and a 1998 Ford Expedition.

The performance that I received from just installing the filter in the Expedition was great. It made the SUV actually drivable in that there was pronounced lag upon acceleration before the K&N Filter which is now gone.  That filter was first installed on Oct. 20 2004, and the filter is 5 years old as of this date.

My Firehawk received its filter in 2002 and is still in use today.

Great Products.
