Description

K&N is the inventor of the Air Intake System and has over 50 years of experience in the performance filtration industry. Proudly designed and manufactured in the USA, this premium cold air intake system is specifically designed for your vehicle and is dyno tested to provide a guaranteed increase in horsepower. It features a high flow intake tube, custom heat shield, and oversized K&N Washable High-Flow Cotton Air Filter for ultimate airflow.

It installs easily in about 60 minutes and is backed by a No-Hassle Lifetime Limited Warranty and will not void your factory warranty. Not legal for sale or use in California on any pollution controlled motor vehicle.Compatible Vehicles:2007-2009 FORD Mustang GT Designed to provide increased horsepower, the K&N 63-2565 AirCharger High-Flow Intake Kit is a quick solution for vehicle owners who are looking for an increase in reliable power. Street legal in most states, installable in 90 minutes or less and built around K&N's High-Flow technology, which utilizes a special oversized and washable cotton gauze air filter and special cold air intake, nonmetallic tubes, the 63-2565 drives a massive amount of air into an engine, which translates into power affordable on virtually any budget. .caption { font- family: Verdana, Helvetica neue, Arial, serif; font-size: 10px; font-weight: bold; font-style: italic; } ul.indent { list-style: inside disc; text-indent: -15px; } table.callout { font-family: verdana; font-size: 11px; line-height: 1. 3em; } td.vgoverview { height: 125px; background: 9DC4D8 url( page/callout-bg.png) repeat-x; border-left: 1px solid 999999; border-right: 1px solid 999999; padding-left: 20px; padding-right: 20px; padding-bottom: 10px; width: 250px; font-family: verdana; font-size: 12px; } How High-Flow Technology Works How does the K&N 63-2565 increase horsepower? By eliminating airflow obstruction in your engine. Restriction of air flow between an air filter and an engine robs even the most powerful engine of horsepower. K&N air intake kits virtually eliminate air path restriction by replacing the standard air filter and the entire air path to the engine. The aerodynamically engineered conduit that makes up the 63-2565 drives a massive amount of air into an engine, which translates into power. This conduit begins with an oversized conical high-flow air filter. This larger filter can fit into the engine compartment using factory holes and mounting points because the K&N 63-2565 replaces your stock intake tube, and air box. This provides more airflow at lower restriction than a standard filter, limited by the size of the factory air box. The oversize air filter also captures and holds more dirt, increasing the service life before a cleaning is required (up to 100,000 miles). The filter is also isolated from high engine temperature by a heat shield designed to lower the temperature of the air entering the engine, which increases horsepower. Affordable, street legal horsepower upgrade. View larger. Measurable improved performance. View larger. Quick and easy installation. View larger. The filter attaches to a rotationally molded tube made from nonmetallic interlaced high density polyethylene (HDPE). This allows for precision shaping of the tube to reduce turbulence and accelerate airflow into the engine. This is why some K&N tubes have unique shapes or indentations that are specifically engineered for each engine configuration. Finally, the tube is connected to the engine with adapters made from high strength materials such as silicon and reinforced nylon and ensures long life. Put all this together and you have the best high-flow intake system available today. Street Legal The K&N 63-2565 is street legal in most states (not street legal in CA – check part number or vehicle listing for specific CARB, California Air Resource Board, status). Systems with no EO (Executive Order) number are street legal in most states, but may not be used on emissions controlled vehicles in the state of California or other states adopting California emission standards. Consult K&N's website to search by part to see which cold air intakes are CARB exempt for which vehicles.

  • Nice product for the money you spend.
Style: 50 State Legal
Was very easy to put together, about the only thing that may throw some off is figuring out what hardware is used where. Take your time and it is very logical. As for the performance of the K&N, I will say the first impressions are very good! It def. kicks up the sound of the engine / exhaust a notch or two! And the response on acceleration is a noticeable improvement as well! It's almost like you can FEEL the car just breathing easier and obviously it is! It just runs smoother even at a normal cruising pace the car seems like it just got a fresh tuneup or something. For the record, I'm a sceptic by nature, so I torture myself about spending money on something like this, because it pisses me off, if I go through the hassle of putting it on and spending the cash to find out the product sucks! This was not the case here, buy the K&N if your in the market for a CAI it WORKS! Be clear here, it doesn't turn your car into a NASA rocket or any s*** like that, you gotta spend a lot more money for that status! Enjoy and hope the review helps you! 06 Mustang GT ... show more

Style: Roto-Molded
This is a great product and easy to install. The pictures in the instructions are not what I would call clear but if you have half a brain you will have no trouble installing this kit. I have noticed sharper throttle response and a slight increase in power. It also seems to have changed the tone of the engine slightly, just a bit more baritone. ... show more

  • Intake Kit
Style: 50 State Legal
05 Mustang GT Conv. After thinking about it for a long while , I had finally ordered the K&N intake! After finishing the install I went for a nice drive on the highway and city streets. I immediately notice a big difference in the cars response from stand still and even better response at higher RPM's. The car now has a GROWL to it when excelerating. I understand you should get some better gas mileage........but I seem to get less now as my driving is much more aggresive. If you are thinking about getting one think no more go ahead. Install was pretty straight forward. ... show more
