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]

I purchased the K&N cold air intake setup No.57-3031-1 for my 2001 Chevy Silverado 2500HD 6.0 and I was surprised to see this thing actually works pretty darn well. So I had to buy one for my 2003 Navigator and they've made a big difference in hp and I also noticed I am getting better gas mileage in both vehicles. I would highly recommend these kits )

Installed in 2010 Lincoln Navigator. 20% increase in fuel economy and definitely notice an increase in power especially when towing. Super easy install. No check engine light issues. Great product. (57-2575)

I purchased a K&N airfilter for my wife's 2008 Lincoln Navigator, wow what a difference the horse power was off the charts. Been watching the MPG and I was blown away went from 12.5 to 15 in town. Way to go K&N!!!!
