Short Ram Air Intakes
Short Ram Intakes bring in a higher volume of air to compensate for the warmer intake temperatures compared to Cold Air Intakes which pretty much levels the field. Some manufacturers like K&N and Volant use a heat-shield or an enclosed air box to keep the warm engine air temperature out which keeps your intake air low so you make more power.
Short Ram Intakes actually allow better air flow because there are less bends in the piping which can restrict the flow of air. The increased amounts of air coming through the Short Ram Air Intake allow for a more complete burn of the fuel and can also help increase your fuel mileage.
Another perk of Short Ram Air Intakes is that they use less materials than a traditional cold air intake so they are usually more cost effective. The lower price and ease of installation makes Short Ram Air Intakes one of the more popular choices when modding a car to get a few extra horses.
