Having a second set of spark plugs has never been a waste of money to me.I'll get w the tuner to see if I should bring a couple sets. It's not on his check list unless it has a Turbo so that could be a waste of money.

You totally missed the point.Well I put 8000 miles on that Saturn in 4 months of working outta town and it never ran better until it’s demiseI was all about mpg on it so either way I’m just explaining my experience not anyone else’s nor am I a salesman! so I’m not trying to argue on FACTS of something that I lived!! So I’m just trying to help out a fellow member here THAT ASKED for help an that he/she has options in that department but maybe you didn’t READ the part that says I have the platinum delcos in my Escalade and recommended them also.
They sure wouldn't work well with "single" Platinum plugs. Half the plugs would have the Platinum on the wrong electrode.The Saturn 1.9l should have copper plugs. I've read many times on the Saturn forum that the wasted spark ignition doesn't like the small electrodes of platinum plugs.
Iridiums are all I have ever used on my 98 Vortec 5.7. No problems.ACDelco iridium plugs are actually just rebranded NGK plugs. The ones in my 2011 Suburban with a 5.3 actually have the NGK number stamped on the outside of the body with the ACDelco number painted on the ceramic portion. The ACdelco are often half the price of the same NGK plug
Waste spark ignitions fire one plug from the center to the side electrode it's companion plug fires backwards.
Double platinum plugs work well with this type of ignition.

That's why they started making "double Platinum" plugs. No matter which side of the coil winding they're on, there's Platinum on the correct electrode.
I learned that when I was adapting GM 4 pin HEI modules and two pin coils to my 82 Yamaha XJ1100. It took me a bit to wrap my head around it.I always heard the term with the Saturn engines, but never knew how it worked. this is the first time i've heard an explanation as to why the platinum plugs didn't work well. I don't think this is common knowledge on the Saturn forum. Those 1.9L engines usually burn oil, so replacing copper is probably the better way to go than buying double platinums anyway.
