The 57 Series Generation II air intake, also referred to as an FIPK®, is K&N's ultimate performance product. These performance intakes are designed to increase power by as much as 10%. 57 Series FIPK's are CARB exempt, street legal in all 50 US states, come with K&N's Million Mile Limited Warranty and are guaranteed to increase power. K&N air intake systems replace your vehicle's restrictive factory air filter and air intake housing. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This translates into more power and torque for your vehicle. The air filters on these kits are washable and reusable. Most of our air intake systems are easy to install using tools commonly available (see installation instructions). [MORE]

Product Reviews      Review part 57-2549

 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.
