Isnt the size 22mm for the holes on the MAC Mids 94-95 style to block the air crap? Well Ive been almost everywhere and cant find any 22mm plugs, so where can I get them without having to order them??? The biggest I found was 20mm.

 

I got mine @ Pep Boy's don't know if you have them down south.

They told me it carries a p/n for a BMW drain plug.

Hope this helps

 

I got mine at Auto Zone. Asked for a M22 drain plug and he handed them right to me.

 

i bought some caps that are for nitrous system from ramchargers and just used the bottom peice from the air crap that fit in the header and put the cap on it and it worked perfect
