Just changed my oil yesterday and took a look at the air filter which was a mess. And with my luck..nowhere in town carries that one. So I figured if I was going to order one I'd make it worthwhile and bought a K&N...I guess I'm wondering if it'll be worth it? Also, I use full synthetic oil so on a normal car you could go 6000miles between changes. But with these burning oil and what not should I still change it every 3000? Sorry about all the questions, not too familiar with the car yet. Thanks.
