Hey everyone just a quick question on what people think. I am currently running a flowmaster si/so. The gotts mod. And a edge evo (with canned tunes) just wanted to know if its worth upgrading to a k&n drop in filter? Worth the money? Any real performance gained? From what iv read seems like a 50/50 some say paper some say oiled. (Thuck is 04 5.4) any input would be great thanks!

 

A drop in shouldn't change much aside from a little more efficiency and a new Motorcraft should do that too. Unless you are going CAI mod, then there's no point to spend the $$ on K&N.

 

Thats what i figuared. No cai for me at this point did the gotts mod and am happy with that. Thanks for the response
