I have a 1999 F-150 4X4, I purchased one of your filters for it at the local Auto Store. I can't believe the power it's giving the 5.4L Triton. Throttle response is there, the truck was by no means powerless before this, but now its very quick! I love your products, and soon hope to purchase the FIPK's! Thank You K&N for being a unique resource for my vehicles needs!

Thank You

The K&N cold air intake kit is great on my 2005 Ford Explorer. I ordered the kit about 2 years ago. I pull a heavy trailer. The explorer is barely big enough to pull it. Installing this kit is a BIG help in letting the engine breathe. It sounds great and makes me feel better too, putting this load on my car. The installation was straight forward and the instructions were excellent. The installation was no problem. Only 2 minor issues. The airflow sensor mounting pad had a casting lap that deformed the mounting surface. I was able to smooth it out with a sharp knife and light sanding. The other issue was that I mounted the filter such that it was riding hard on the bottom of the intake box. This was my fault. I didn't find out until I took the filter off to clean and re-oil it and found a very small worn spot on the filter. When I install this new filter I will make sure that the filter is free from interference all around. Thanks for a great product I'll be using K&N from here on out.

Have installed K&N on my last 4 vehicles: 2010 ford F-150 , 2011 Chrysler 300-C 5.7 Hemi, 2012 Jeep Grand Cherokee 5.7 Hemi, 2013 Dodge Charger SRT-8 6.4 Hemi. And I have been pleased with the performance and sound from all four.
