I never saw JLT on an ordinary 5.0 L Mustang, I have a friend who got a Mach 1 whit a JLT paint color match also some owners of Cobra 2003-2004 install one.
In fact if you got a got filter the quality of the tube are not so important, an Ebay CAI at $25,00 can do the job, even if it look cheap, if you replace the air filter by a good one your in business for less money.
