Less than 10 days to receive! Great Service and instructions were awesome ! Less than 1 hour for install. Took for a drive being the roads are ice and snow it was tough to measure extra power but I can say there was some difference. Waiting for some real dry roads. When you pop the hood on my Ford Taurus SHO twin turbo it looks so great! Merry Christmas from Canada!

I have been buying K&N filters since 2003 for both my 2003 and 2005 Lincoln LS V/8's and now for my new 2010 Ford Taurus SHO P2. The increase in horsepower is palpable, the extra power is obvious and the low profile growl from the exhaust is pleasing on the ears. I would recommend this product to anyone looking for an in expensive way to increase your vehicle's horsepower, I even put one in my 2007 Lincoln MKX and again the power was Bang in your face fast. I'm Looking forward to getting the Cold Air Intake for my SHO once it's available.

I recently experienced a failure in a component of my 57-2541 Cold Air Kit after 100,000 trouble free, fuel saving miles. The problem was easily diagnosed and repaired by me at home. I contacted Elzabeth Taylor in Customer Service who was extremely helpful and very understanding in regards to my situation. She instantly shipped me a the part to replace the part that I field fixed in my driveway. She requested that I take some photos and send them to her so that Research and Developement could take a look and make any adjustments if necessary. I was delighted to comply and sent them back to her later that evening. I have K&N Cold Air Kits in my 1999 Ford F-150 and my son's 2013 Chevy Sonic 1.4 Turbo. I have an air filter in my wife's 2012 Dodge Caravan. Your products have served us well and delivered the performance figures that you quoted. Actually, I got better than quoted performance on my 1999 F-150. I averaged over 1.5 mpg increase after the intallation. I will be purchasing a Chevy Silverado with a Duramax Diesel engine very soon. I am anxious to see what we can do with K&N products at that time. Keep up the good work and the great customer focused service.
