I just hit 170,000 on a 2000 4.6. I'm thinking of going with an Airaid intake. Anything I should watch for or any concerns adding something like this to a high mileage engine? Also, I understand that I should get a little bit of a power increase with an aftermarket intake, but will it kill or help any on gas mileage?

 

its gonna give you more power regardless also a way to trick your truck is to reset the computer after the cold air intake to make it think its stock adds allitle more gas miliage depends on ur driving sytle u will see more power just depends u gonna still granny drive or have some fun mine went down lol
