Street legal, 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 57-2546-1 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( amazon.com/images/G/01/electronics/detail-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 57-2546-1 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 57-2546-1 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 57-2546-1 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 performance improvement. 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 Many K&N intake systems are street legal in all 50 states and include a California Air Resource Board (CARB) Executive Order (EO) number that ensures the kit has been tested to comply with emissions standards. EO numbers apply to the kit as well as the year, make and model it is being installed on. Systems with no EO 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.

  • 6.0 f250 powerstroke
Fits great and easy to install. Took about 45 minutes and in. Way better airflow and you can notice it! Milage did seem to increase and throttle response was much better.

  • 3 hours from delivery to finished
I got it delivered at 1:15 pm And it was fully installed by 4:15. No air leaks, no issues, sounds great. I’m happy. Just take your time and do it right the first time.

  • SUCK IT IN!!
What a difference on my Excursion. You can really hear it suck the air in. A little noisier, you can hear a turbo whine a little more on the diesel. went on a trip and noticed a little more power and 1mpg better than usual. Once the turbo back 4" exhaust goes in, I'm sure it will be the complete package. If you do this do the exhaust also, preferably with a cat delete. It'll open it all up! Otherwise its like sucking in with a can and blowing out with a straw. You just won't get the performance you intend to get. But there was a 6% increase in gas mileage. And a 5% increase in HP. ... show more

  • not complete
Ordered this for my 2006 F250 Super Duty and it does not come with everything to install it. Now I'm going to have to send it back they send me a complete kit. K &N does not have customer service on weekends, go figure.

  • Well worth the money!
It performs better than I expected. It's like nothing is holding the truck back when I step on the gas. I've also noticed a nice increase in horse power. Not only that, if you've ever tried to take out the factory air cleaner to clean or replace, this eliminates that headache. I also like the fact that I can see the condition of the filter and not have to guess how dirty it might be. ... show more

It fits. I think the “box” it going to allow dirt and debris by. Probably have to clean filter a lot

  • K&N FIPK filter is an excellent product.
Bought this for my 2005 F250 power stroke and after running it for about 1 month it looks like the mpg increase is topped out at 1.2 mpg increase. Sounds great at accelleration, easy installation, and recommend to all my friends.

  • Good build quality; excellent instructions
Fits Ford 6.0 L Powerstroke. Fairly easy to install. Excellent instructions. It’s worth reading over instructions two or three times with a highlighter, since multiple intake configurations are covered. Highly recommended.
