Im new to tuning vehicles and i have always heard good things bout K&N i was just wondering what the major differences are cuz every1 on here seems 2 go with the AF1 If u could give me the pros and cons i would appreciate it

 

The AF1 is supposed to provide the most gains on the Ford trucks. I think it however, is the most expensive intake. A lot of people who use it also have gotten CELs after installing them. There have not been that many posts of CELs after K and N intake installs. The AF1 also has a shiny intake tube and heat shield so it looks pretty good. I have the K and N and its ok. I dont think the difference in the two is that big of a deal but just my opinion.

 

I just installed the AF1 last weekend. It was pretty easy.......I didn't throw any
codes and it's been about 250 miles. Sounds great and seems to add some power to the truck. I took some pics...if you want to see what it looks like just go to my gallery. Good luck
