Up for your consideration is a NOS genuine Ford Autolite UNOPENED box of 10 BRF42 spark plugs.  The Ford part number is D0AZ-12405-A.  This is the finishing touch to your engine compartment.  You get all 10 in an unopened box for one money.  You may not get the exact box pictured, but the pictures fairly represent the box you will receive.  (I have just 4 Autolite 10-packs left.)

CAUTION:  It has been my experience that often there is surface rust on the black part of the plug even when in this undisturbed condition.  This is generally easy to remove with a soft brass brush and some WD-40 (Don't use power tools!!!).  But this will leave the plug with a brown-black mottled appearance at the base which generally is very difficult to see once installed.  Understand all this before you decide to bid.  Read also the fine print below.

FINE PRINT:  As with any NOS part, there is no return if any attempt is made to install it.  I will accept returns otherwise for any reason, just keep the part in NOS condition.  Buyer agrees to these terms before bidding.  Quoted shipping is to the Lower 48 United States only.  Purchasers outside the Lower 48, please wait for my invoice.  You will be charged only the actual freight to your address.
