Short ram air is the most commonly used air intake system, because of its affordability and its easy application. But has a huge drawback. Short ram air is also known as "warm air", and this is a common mistake made by inexperienced owners. Although the short ram is very popular it does little to produce cold air within the intake because of its location in the engine bay. Even though heat shields are sometimes added to the installation, you're basically dressing up your engine with little or no extra performance. Some manufacturers will give you the specifications on the "potential" for extra horsepower and performance, but reading the fine print will save you money as well as save you a headache later on.
