K & N is the way to go!
Overall, the installation was a breeze, with one exception. The breather tube provided was a tad too small to connect to the valve cover, so I merely joined the factory hose with the hose that came with the kit. This product will wear out your tires if you do full throttle launches! LoL I did notice a bump in fuel economy when driving lightly. (about 4-5 mpg in the city) If you like your engine to be quiet, don't even bother. I personally LOVE it! I love the growl!
