If it's a 2.2 then the K&N or just remove the big resonator under the air box and see if that helps. It's more of sound than anything.

Ya not looking for power. Just looking for sound. I know u get next to no power gains from doing this.

I have their Typhoon intake by K&N, good on sound, not really a HP gainer. They claimed 6.6HP on the 2.2L which sounds about right cause you wont really feel that little of gain, but you will notice some slight throttle response increase.

K&N Drop in type will not do a thing until you remove the bottom resonator chunk out, then you will notice a bit of sound.

I don't know what K&N is basing that horsepower gain off of, but it's much too optimistic a number for a stand-alone mod. Same deal regardless of brand or type. But since it's sound you're looking for and not necessarily power, I would think an SRI would be your best choice. Other advantages is higher under-the-hood visual appeal and you don't have to worry about puddles.

Check if your car is equipped with an SAI. If it is, it'll narrow down your options for an intake.

I've got an Injen CAI on my '06 L61. It sounds good and you do feel a little more pull at higher rpms, but you might also feel a slight loss of low end grunt. The thing is, torque comes from restriction. If you cut down on restriction, you'll lose torque in exchange for high rpm power. That goes for any bolt-on that depends on airflow. A tune may be able to resolve that somewhat down the road.

True to a point Plain Jane. You do not feel horsepower, its just a method and schematic to sell customers. Torque is the ability to work or move. If you add an intake to your OEM rest of the car, the only thing you will notice is sound more than anything. You might gain a few ft lbs but nothing like a turbo upgrade.
Manufacturers build and research these engines to meet EPA and OSHA standards across the 50 US States and other foreign countries standards. You may think there are restriction points, but really in today's world of engines, there are none. Actually, some manufacturers have parts that work better in flow than what the aftermarket can provide. You just need an equal balance of flow through the engine is what your after in performance.
So if you plan on upgrading your intake system, you may want to consider the parts it connects to (throttle body, intake manifold, bigger head port size), then have it follow through after the combustion process, header, downpipe, cat-back system. Then a tune will be needed to balance the correct air/fuel ratio mixture to combust properly.

Just remember your engine is nothing more than an air pump, it needs air to pull in and push out.

Yup. Ever heard of the bottleneck theory? Your system is only as good as its weakest point. Improving just one link won't result in a better chain.
