K&N - The World's Best Air Filter
K&N’s lifetime replacement air filters are designed to increase horsepower and acceleration while providing excellent filtration. K&N air filters are custom designed to fit into your Lightning's factory air box. Their drop-in design means adding performance is simple. Simply remove the disposable air filter from your Lightning and replace it with a K&N; there is NEVER any cutting or fitting required. K&N stock replacement air filters for Ford Lightnings are covered by the famous K&N Million-Mile Limited Warranty and will be THE LAST AIR FILTER YOUR SVT WILL EVER NEED.
Why is Air Flow Important?
More air entering your Lightning's engine can increase combustion efficiency, resulting in more horsepower and acceleration. K&N air filters are designed to reduce air restriction allowing your Lightning's engine to breathe more air. A clogged air filter can have so much restriction that it can even degrade your gas mileage. Remember.. an engine with a restrictive air filter is like a person breathing through a straw.
An Ecological Alternative to Disposable Air Filters
Over 100 million disposable air filters are discarded each year. K&N invented the reusable cotton air filter to help reduce this waste burden, and have sold over 20 million since 1969. A K&N air filter is cleanable and will last for the life of your vehicle. Instead of paper or synthetic materials, K&N uses multiple layers of threaded cotton gauze. The natural characteristics of cotton help to create a remarkable filter that can provide outstanding filtration and very high flow rates.
Clean Every 50,000 Miles
This filter requires cleaning every 50,000 miles for highway use, more often in dusty or for lowest restriction.
K&N Air Filters are Tough on Dirt
Thousands of microscopic cotton threads absorb K&N's specially formulated oil to create a powerful filtering medium. As part of their ongoing commitment to protect your SVT F150's engine, K&N verifies their filtration efficiency using the ISO 5011 text protocol.
K&N's Million Mile Limited Warranty
K&N replacement air filters are built so well, that they warranty them for 1,000,000 miles! This means you can count on them to continue delivering engine protection and high airflow for the life of your limited edition pickup.
