Absolutely the best customer service I have received. Obtained a warranty replacement air filter, shipped the next day and is scheduled to arrive tomorrow. No hassle, friendly and I will never use anything but this air filter. Both my vehicles use K&N air filters. 2011 BMW Z 4 and A 2008 Jeep Wrangler. The sound and the added power that comes from adding the cold air intake is wicked cool. I am, and will always be, a life long user of many K&N products. You guys Rock!

Just what I wanted - great quality, but a bit pricy.

Started using K&N filters over 30yrs ago on off road toys and never stopped. Porsches, Jeeps, Toyotas, etc. High quality and last many years if properly cleaned and treated. Thank you from a satisfied customer, Chris

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.
