Cold air intakes are a common modification because they tend to be relatively cheap, easy to install, look good and often improve engine sound significantly. All in all, a must have in every tuning project. For those of you who are totally sure of installing a new intake system for your car, you should realize one fundamental point before you modify anything on your ride. As a rule of thumb, always ask why the stock setup is the way it is. Engineers invest numerous hours designing an intake system to be the way it is. Stock set-ups are typically designed foremost with noise restriction in mind. In addition, they are also designed to preserve your stock air filter by protecting it from harmful elements such as water, dust and other road debris. When you replace your stock intake unit, note that you are compromising these important attributes. You should also realize that your power band will be affected as well. A cold air intake will often improve upper power band at the cost of diminishing power in the lower rev range. However, power gains typically vary in the range of 0-15 HP in the top end. In some forced induction applications, you might even be harming your power band all together. If you're not after high end power gains, you probably shouldn't get a cold air intake system.
