|WHAT ARE AIR INTAKES?
How Performance Air Intakes Work
All cars and trucks come with a factory air intake system. It usually consists of an air filter inside a plastic box that gets air fed into it on one end and passes filtered air through the other side into an accordion shaped hose that feeds into the engine's air intake. Factory intake designs are created to meet several objectives. They must be cost effective and provide filtered air to the engine while keeping sound to a minimum.
A performance air intake typically takes the place of the factory intake system. It usually includes a high flow, low restriction air filter connected to a custom designed low restriction aerodynamic tube that connects to the engine's intake. A review of most designs will reveal a heat shield that shields hot engine air from entering the air filter. Cooler air contains more oxygen molecules which helps create more horsepower. Sometimes designs where the filter is located in the engine compartment are referred to as "short ram intakes". Cold air intakes (CAI) place the performance air filter outside the engine compartment where cooler outside air can be obtained. These usually don't have a heat shield.
Good quality performance air intake systems add horsepower and torque (acceleration) while protecting your engine. Many consumers report better gas mileage with air intakes, however, much of that depends on how you drive and other factors.
Good quality air intake brands include K&N Engineering, AIRAID and AEM Induction Systems. These air
intake brands are made in the USA, stand behind their products and have
customer support based in the US. K&N has been manufacturing
performance air filters since the late 1960's, AEM was a pioneer in cold
air intakes for sport compact vehicles and AIRAID has their own unique closed and open designs..
K&N air intakes use a performance air filter made from oiled layers of cotton fabric. K&N air filters are washable and reusable. Their air intake air filters can go for up to 100,000 miles before they need to be cleaned and re-oiled. K&N air intakes come with a million mile limited warranty.

AEM air intakes use a synthetic air filter that is washable and reusable.
These filters don't use oil. AEM air intakes come with a limited lifetime warranty.

Beware of air intakes with low quality air filters. Air intake air filters need to flow well but most importantly they must protect your engine for long life.
