Ram air intake aka, short ram intakes are good for low end
horsepower and torque
Cold air intakes have more horsepower gaines then short ram and
more top end power.
If your looking for more torque then horsepower, meaning more
acceleration but dont care about topping out your car, then short
ram intake is what you want.
If you already have enough torque and just want more horsepower
and go fast as possible, then cold air intake is what you want.
