Has anybody tried the Delphi Opti Spark. I believe that Delphi is a GM company. Is the Delphi as good as the AC Delco?

DELPHI is GM - It's an on-again, off-again GM parts division that sources, makes, and supplies so many different parts that you can't ever list them all - back to the 90s.

Google "gm parts division delphi".

An optical trigger within a distributor cap?
Is that what that is?

 

[Submariner409]

Yup - several automobile brands and several aftermarket brands used it for years. An infrared beam rotating trigger wheel.

Some call it magic...

I would avoid it on anything using the standard distributor cap and rotor scheme with induction coils.

If/when mime fails, I'll buy AC Delco.

...Change the water pump (OEM) at the same time if money is no object.
