For sale is an NOS 6424750 Ram Air III IV V air cleaner sensor. This is the ultra rare 1969 only sensor. It is correct for 1969 GTO/Judge and Firebird/Trans Am. This part number was discontinued and replaced by the more common 6484242 sensor in March of 1970. I purchased a couple of these from a friend in Europe and this is the last one I'm selling.  This is the part the 1969 Trans Am and Judge left the factory with. I put a picture from my 1969 Pontiac parts book. This part number crosses over to all GM car lines except Cadillac. I do not have any other parts books other than Pontiac so please check your listing before purchasing. Buyer to pay 10.00 shipping and payment in 3 days by PayPal or cash in person.   Thanks.
