It was a perfect fit. A little pricy, but if it meets up with its description, its worth the price. I will be ordering another one for my second car.
Eric Causey, Bedford, Texas
I use K&N in all my autos(2008 Passat, 2010 Golf, 2010 F150, 2011 Pathfinder). Have for 20 years now, hands down the best filter on the market.
