It only takes 90 minutes to reap the benefits of a K&N cold air intake system One of the
fastest ways to add more airflow, horsepower, and throttle response to your car while still protecting the engine is with a cold air intake. The way an engine works is by taking in air, mixing it with fuel, and combusting the air/fuel mixture, which then sends power to the crankshaft and onto the transmission. The more fuel you can add to the mixture, the more power you can make, to a point. But if you just add fuel without increasing the amount of air in the cylinder, you will run the engine
rich and lose power. That is where the cold air intake comes into play. K&N air intakes provide a less restrictive, more direct path for
air into the engine This particular intake is from K&N Engineering. They have been making cold air intakes longer than any other company and are the worldwide leader in cold air intakes for cars and trucks. As you can see, the air intake tube is made of a black plastic, which is called high density polyethylene, or HDPE. This material allows the engineers the ability to maneuver around obstacles in the
engine bay when looking for the best airflow path. At the end of the tube is a signature K&N red washable air filter. These filters are made from multiple layers of cotton filter media that has been treated with a special oil to help stop contaminants that can be harmful to your engine. Around the filter is a custom aluminum heat shield. When the hood is closed, it seals against the weather stripping on the heat shield, making a sort of air box that helps prevent the intake from ingesting
hot engine bay air. That is where the cold in the name comes from. If you ever questioned the power gains, here
is a 2007 Ford Mustang Shelby GT500 dyno chart: 56 hp! Companies like K&N typically offer several different cold air intakes for vehicles. These vary by type of materials used in the intake tube, to type of filter: from a traditional oiled cotton media to a non-oiled synthetic media. The choice is ultimately up to you. One cool thing about K&N intakes is that they come with a 10-year/Million Mile Limited Warranty and are guaranteed to increase the horsepower
of your vehicle. Check them out to see all the intakes they have to offer.
How much HP gain from cold air intake and exhaust?That's why a cold air intake is a small investment with a rather big payoff. It makes such a big difference, in fact, that the simple process of redirecting the filter to draw cooler air is good for a horsepower gain of about 5 to 20 ponies in most cars.
How much HP does exhaust add?Everything that comes before the muffler, where the pressure is greatest and performance potential is highest, will remain tight and congested. MagnaFlow, an aftermarket exhaust manufacturer, says that its customers can expect horsepower gains of around 10 percent (which is a pretty commonly-quoted figure).
How much HP add cold air intake?How Much HP Does a Cold Air Intake Add? When upgrading your air intake, truck owners can expect an increase of between 5 to 15 horsepower, though this number can be higher or lower depending on your make, model, engine size, and type of intake.
How much HP does intake headers and exhaust add?So how much hp do long tube headers add? If attached to a stock engine, you can expect about 6-9 hp over a manifold.
