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 57-2530 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 57-2530 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. 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.

  • GREAT INVESTMENT
2002 Excursion with the 7.3 diesel. Love this vehicle and will keep it forever. Already had a K&N filter, but broke a fitting on the air filter box when cleaning the filter. The cost to replace this part was almost as much as this new cold air intake unit and I didn't want a 10 yo part from the junkyard since it would have the same weakness of the part that just broke. It was easy to install and I am impressed with the performance. It is louder and it made me nervous that I had a leak, but after numerous stops to check I was sure that it was ok. The computer mpg shows a 2 mpg increase, but I have yet to check it the more acurate way. My hubby is happy that he now has my old K&N filter and it has improved the performance on his truck. I wouldn't have done this without the part breaking, but I am glad that this was my decision instead of going back to the original air filter box design. Update 1/9/12 - Still very happy with this and I am really getting an average of 2 additional miles per gallon. May not seem like a lot to most of you, but this vehicle costs over $150 to fill up due to the 44 gal tank. The idiot computer read-out shows that I am getting 22.7 miles to the gallon. Thanks to my super chip programmer, the mpg readout hasn't been accurate since I programmed it when the vehicle was new. I am actually averaging 18 mpg and I live in the hill country in Texas. ... show more

  • Well worth the money!!
2000 Ford F-350 DRW, 7.3L diesel engine, flatbed work truck. I work in dusty conditions living in Arizona. the truck has lots of tools on it and pulling equipment all the time. Ford recommended the heavy duty air filter, so we removed the stock one and we installed it. running the ford recommend air filter, we averaged about 6 miles per gallon and always wondering why the truck seam kinda of sluggish. The ford filter cost about $100 to replace every 5,000 to 10,000 miles. I don't know why I didn't think about K & N filters. Installing this unit got great results. you will hear a change in the engine sound, I like it. 12 miles per gallon and more power, the engine runs like a new truck. it has already paid for it self. ... show more
