Perfect fit and high quality.
Size: (Pack of 1)
Good product, not much to say. The product arrived quickly, looks to be of high quality construction, fit perfectly and took me only a couple of minutes to install. I love it when a product is no frills and delivers as advertised. I've used various filters from K&N before and have always had very good success with them so I will be buying more of these for sure when the time comes.
