OP, I fixed your title so you can get a better view count. You might want to do some more research too and determine what manufacture you want to go with. There are a handful of options all with their pros and cons. Quite literally a million threads to search through.
Had a K&N for my Base, priced right but my only reservation about it was that it was supposed to seal aganst the hood. Not sure if it was tight enough. For my GT I got a Volaint, like it better for 2 reasons is the filter is enclosed for a good seal. Also it has a snorkel that goes down into the nose closer to cooler air, also a HSRK kit to measure cooler air. When it gets nice i most likley cut the piece on the lower grill to get more air to it. Just my openion..
