Hey just wandering whether or not it is worth, adding a K&N air filter to a 2007 GT Sedan, or not, I've heard that it already has a hiflow filter stock. But could I get some extra horsepower by adding a K&N
Yeah, not worth it. Maybe in a year or two when you actually NEED to replace the air filter because it's super dirty, upgrade to a K&N. But the difference will not be noticeable so don't waste your money now.
