K&N Performance Cold Air Intake System: Easy Installation, Engineered to Maximize Airflow, Boost Horsepower & Torque, 77-2514KP

2000 F150 5.4L 4x4. Like I said, I spend more at the pump because I love the sound of the air filter sucking in the air as I mash down on the gas pedal. Throttle response is incredible. I installed the cold air system on this truck with in a few months of owning this truck. I now have 384,188.9 miles to date. I bought the truck on 12/24/2000 NEW with 45 miles when I bought it. I also run a dual oil filter and of course they are K&N HP3001

I put on an intake system on a 1999 F250 5.4. The instructions were easy to follow, all parts fit perfect. This truck is use to pull a 27 ft. Airstream so when we get back from Florida in Nov. I will comment on performance, but from test drives this truck runs great. What an excellent product.

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.

Great equipment stuff you all have. Been using k&N filter systems for 13 year, won't use anything else. Thank you all for your help.

Quicker response when you hit the gas.
