K&N has been a leader in the filter industry since they were founded over 36 years ago and starting back in 1992 they decided to test the waters of the Mustang Intakes world. At K&N they feel that the best bang for your buck or dollar to horsepower investment can be found in their intake systems. Built for horsepower they boast that if they can't boost a cars horsepower they do not make an intake for it. With a promise like that you know that your Mustangs Performance will be increased. They increase the horsepower starting with their million mile warranted filter system and high flow technology. The K&N Mustang Intake is also legal in all 50 states so it doesn't matter where you live, you can improve your Mustang Performance.
K&N Mustang Intakes have some very impressive numbers. For example the 2003 Ford Mustang SVT boasts of an impressive 30 HP. Many times the exact same vehicle will perform differently than another. When K&N uses a number for HP it is an average of runs and not the biggest gain they have obtained. When buying and researching if it says you will get 10 HP that is the bare minimum you may actually get more out of you K&N Mustang Intake.
The size of your air box is one of the main reasons that K&N Mustang Intakes are so consistent with their increase in HP. Believe it or not they completely remove the air box, meaning there really aren't any restrictions on how much air is moved to your engine other than physics. They use a large conical open element air filter, which provides more surface or intake space to maximize airflow. And we all know that maximized air flow translated into more HP. This oversized air filter catches more dirt so you don't have clean the filter as often. And you will never have to replace the filter because of their 1,000,000 warranty.
The next area of improvement is in the design of the air path or High Density Polyethylene tubes which are black and for those of you wanting a silver colored tube they do have aluminum. If you are looking for more power then go with the black Polyethylene but if you are all about the looks definitely go with the Aluminum. Either way you will have high gains from any of the K&N Mustang intakes.
K&N Mustang Air Intakes or
Mustang Cold Air intakes in general are great
