Cosmos intake isn't as good as people say.
Intakes respond better to air velocity, not air volume. If you have a long, thin pipe that will suck the air in faster, and while the dyno will show a few horsepower lower, the throttle response and "jump" of your car will be ten-fold. The cosmos is probably better for a few hp up top, but off the line it hurts you. Yesterday I rode in a 325 that proved this and made me a believer.
