Review on 🚀 K&N Cold Air Intake Kit: High Performance, Increased Horsepower Guarantee: Fits 2004-2005 FORD (F150, Lobo) 77-2557KP by Christopher Jackson

block fits with no problems. The instructions are good, but it's best to take the time to lay out all the parts (especially the screws) so you have all the parts you need for each step. We didn't make it and ended up having to go back to change the bolts. The fit was good and easy to understand. The only thing that was unclear was that the air horn embedded in the fender should be removed together with the old air filter housing. I don't know more power, but the sound is great. Before starting, disconnect the battery (negative) cable and follow the instructions in the vehicle's owner's manual, which explains how to relearn the computer after the battery has been disconnected. Retraining instructs the computer to use the new mass airflow readings to improve the performance of the new air intake system.
