Either one will do the job. Some people don't like the K&N kit because it leaves the filter under the hood, where it will suck in warm air from the engine compartment. But I don't think it makes THAT much of a difference. Just about anything is better than the stock box unit!
I say, get the K&N kit, then if you can afford it, get the C&L intake tube to complete it. Or call K&N and get one of their CAI's because the tube they use is made of a plastic rubber material (I think...)
