Review on Boost Horsepower with K&N Cold Air Intake Kit for 2005-2008 FORD F150 (57-2572): 50-State Legal and High Performance by Tom Duncan

what else can you say except that it's k2n cai. everything went very easy, I didn't even use the instructions lol it wasn't necessary but maybe it's just me. it took about 45 minutes, was pretty easy to install, fits great, sounds even better. I put a single or dual flow exhaust on my truck and when I added this my exhaust got a deeper and smoother tone like the v8 model is 4.2 v6 for me but overall I am very happy and can do this Highly recommend the product to anyone looking for a little lower level and a little more fuel economy the best hit for your beech.
