"05/17/2024" GOT ANOTHER ONE IN and it is sitting on the shelf ready to be shipped out quickly unlike many sellers who dropship and do not have them in stock ready to go out. Almost every one of them also have pictures of the early non-vented opti which is not correct for this part number and not the one you are actually buying. Our pictures are of the actual and correct part!


"09/25/2019" People keep asking me if this Opti used the original Mitsubishi sensor or not and to be perfectly honest I have not opened one but someone on the Impala SS forum busted one of these open & confirmed that it is the sensor being used.


"09/25/2018" This is a Brand New Remanufactured Opti-Spark from GM. General Motors has begun selling remans again.



Here we have a Brand New Factory Remanufactured Optispark Vented Distributor that is Part #19383531 that we were able to pick up from GM. It is a Genuine A/C Delco Factory Part with the correct part number dot stamped on the side of it! The Original part #1104032 has been LONG Obsolete and was replaced with GM Factory remanufactured replacement part #19212300 which is also No longer Available from GM. Now GM has begun offering a new Remanufactured Opti with part #19383531 and this is one of those parts. It is used on the Impala SS, the 9C1 Package Police cruisers and other vehicles as well. It is coming from a Chevrolet Dealership so you know you will be getting a first rate part and not some cheap aftermarket part. There just is nothing like factory parts! Thanks for looking and Please look at my other auctions for more Caprice and Impala SS parts.

We would also like to let you know from our past experience that if your original Opti-Spark failed due to moisture getting into it then we HIGHLY recommend that you also replace the Vacuum Harness for the Opti-Spark to prevent possible contamination of the new Opti-Spark which possibly could cause damage to the new Opti-Spark. the Harness is Part #12555323 but it is NO LONGER available from one of our other auctions due to GM discontinuing it.


This part should work with a variety of GM/Chevrolet vehicles like these with either the 4.3 Liter or the 5.7 Liter LT-1, and may fit other vehicles as well as long as they have the VENTED Opti:
