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.

After reading other reviews I decided this was the intake for my 2013 Ford Focus with the 2.0L Duratec engine. Great sound and noticable performance, plus better fuel economy. The numbers don't lie. The provided dyno info was almost exact when I had put mine on the dyno. Nearly 10hp gain through the meat of the power curve.
