What is a makeup air filter inside the normal air filter that I am supposed to replace?

I drive an '04 Dodge SRT-4. In the manual under maintenance schedules it says both to replace the engine air cleaner filter and it also says to ';Inspect and replace, if required, the the make-up air filter (located inside the air cleaner)';





What is the Make-up air filter? I replaced the main air filter and looked inside of it but there was no other filter inside of it.What is a makeup air filter inside the normal air filter that I am supposed to replace?
YOUR VEHICLE IS NOT EQUIP WITH THIS TYPE OF AIR FILTER.What is a makeup air filter inside the normal air filter that I am supposed to replace?
Make up air refers to extra air the engine needs under high demand situations. The M.A. supply vent only opens when the throttle is nearly wide open, the normal air intake under these circumstances can't supply the required C.F.M.'s. It is usually an extra supplied with high performance models or can be purchased ';after market';. Your vehicle apparently is not so equipped.
