How Much Horsepower Does a Cold Air Intake Add?

Cold air intakes are said to be a popular modification for those who are just starting to modify their car, as they are relatively inexpensive and easy to install. They can provide a decent power boost with a small investment, with the potential to increase your vehicle's performance by between 5 and 20 horsepower. This number will vary depending on the make and model of your vehicle, but it is enough to give your car or van some extra energy when walking. The reason cold air intakes are so effective is that cold air is much denser than hot or warm air.

Colder air carries more oxygen, so if you can help your car get to the air that hasn't been heated by the engine, that extra oxygen will be better used with the same amount of fuel. A cold air intake allows the engine's air intake process to absorb colder air, increasing performance and efficiency. A high-performance cold air intake is often an improvement over original or standard equipment, even though most vehicles were manufactured with an air intake system that efficiently prevents hot air. Cool air intakes funnel cooler air to the engine, which can lead to more efficient combustion and better fuel economy.

Most kits include a high-performance filter, sufficient tubes to relocate the filter, and often a cold air box that helps separate the air supply from the heat of the engine compartment. The ability to increase engine noise is one of the main reasons why people choose a cold air intake filter. With a second-hand cold air intake, tubes are included to relocate the air filter away from the engine so that the air sucked in is cooler. Smaller engines without a turbocharger will most likely not experience a noticeable change in performance if they install a cold air intake. In terms of power gains, tests have shown that installing a cold air intake on an 8-cylinder engine such as the LS or the Coyote can result in an increase of 15 to 20 horsepower. Warmer weather can also be a factor in power gains, as tests have shown that if temperatures had stayed below 50 degrees Celsius, the real gain would have been closer to 7 or 8 horsepower.

It is important to note that if you buy a cheap cold air intake kit with a faulty engine air filter, it can also damage the engine. Therefore, it is important to make sure you purchase a quality product from a reputable manufacturer. In conclusion, cold air intakes are an effective way to increase your vehicle's performance by between 5 and 20 horsepower, depending on the make and model of your vehicle. They are relatively inexpensive and easy to install, making them an attractive option for those who are just starting out with car modifications.
