I WAS WONDERING IF ANYONE KNOWS?
I HAVE A 2001 F-150 5.4L
I WANTED TO PUT ON A NEW AIRFLITER SYSTEM ON IT. I CALLED K&N AN THEY SAID THEY WONT HAVE ANYTHING TILL AFTER THE HOLIDAYS . I CALLED AIRAID THEY SAID THAT THE 97-2000 KIT WILL WORK FOR THE 2001 TRUCKS HAS ANYONE TRIED IT?
THANKS FOR YOUR TIME GUYS. U GUYS HAVE BEEN A VERY BIG HELP TO ME

 

The engine did not change from 2000-2001. Both will fit. I think they have to get it certified for each model year before they can market it for a specific model.

 

K&N just got 2K certification done last week.
