Review on 🚀 K&N Cold Air Intake Kit for 2005-2006 Ford (F250/F350 Super Duty, Excursion) 5.4L V8 - High Performance, Guaranteed Horsepower Increase - 50-State Legal - 57-2570 by Brendan Baker

I checked several cross references to determine the right kit for my 2007 F250 XL truck (5.4L petrol). Upon receipt it turned out that this was not suitable for my engine. I consulted K&N who eventually got back to me and said that the 2007 F250 changed the engine mid-year and found that I needed the 57-2570 kit instead. However, they could not guarantee compliance. I took the opportunity to return this kit (great service from Revain) and ordered kit 57-2570. It fits perfectly. Great prices and service from Revain.
