I got a K&N intake for my '06 Pontiac GTO soon after getting the car brand new. My recent purchase was a replacement filter for that intake. K&N makes great products that should come as standard equipment on all performance vehicles. The car ran better, faster and sounded like the muscle car it is as soon as I installed the intake. It's only logical that a car can run with more power if it can breathe better. If you had athsma you wouldn't participate in a track meet without an inhaler. The same is true with petrolium powered engines. Thanks for your contribution to auto enthusiasts everywhere!

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.

This is my second filter, the first has 200,000 miles on it with proper cleaning and maintenance. These filers will last a good amount of time. But I have to say once replaced my truck acts like it's brand new, I can tell you this this fiilter is worth every penny. Do yourself a favor and get one.

Kind of difficult to find what filter was needed for my intake, but overall am very happy with the performance and glad I had no problem installing it.
