I only have a K&N filter on my X because it came with the truck, otherwise I wouldn't have bothered with anything else other than OE. It's not really a performance bearing car with the 3.0i. I mean Dinan stage 3 for the 3.0i maybe nets you 15 hp at most? And thats exhaust, intake, software, throttle body etc.
