Nitro I didn't think the PT had a waste spark system, but after checking the service manual, It is. It is two coils in the pack that fire paired cylinders together. 1 and 4 as well as 2 and 3 at the same time. So yes, double platinum spark plugs would be useful on the PT Cruiser. As for your .042 spark plug gap.... Definitely gonna give that a shot.

Rule No. 1 of plugs is: THE WORSE THE IGNITION YOU HAVE, THE MORE CRITICAL IS THE PLUG SELECTION
If you've got a OEM ignition many times posted information about its level of performance is from people who have never really seen what an ignition system does above 3000 RPM and assume to much. Perhaps some should be picking out platinum plugs to make up for the weak ignition.

With a good ignition system THERE WILL BE NO MEASURABLE DIFFERENCE IN POWER, MILEAGE OR PLUG LIFE BETWEEN THE NEAR RIGHT AND PERFECT PLUG CHOICE.

Like I always love to tell people.

For this... It will work, until it doesn't.

Once it works.... can't get any better.

LOL I have already built a 4 coil system for myself and another PT Cruiser owner...and I also have used waste spark system on another platform Chrysler engine for years with a "knock your socks off" ignition system.


BTW most all my PT Cruiser 1/4mile passes (almost 80) are on #470's with a 75 shot of N20.
The platinums are a waste of money IMHO!
Hey its your money $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$

I was saying the Double Plats have some use if your intent is for longer life on a single set of plugs.

I run the #470 in mine. I wish I had a 75 shot of N20 in my car.

I run the Champion Double Platinum #7570 in mine. Put them in at 60K and have 124K now. Starts at first turn every time, smooth idle and goes right up to red line if needed without hesitation.

I think my car had the original plugs on it until last year. Until then, it started immediately, idled smoothly and would pull great, though I generally stay pretty far below redline. I changed them when I started chasing my misfire. One had a .8+ gap. Had to double up on the feeler gauges to measure it. The plugs weren't causing the misfire.

ok...now go and try and stomp on your throttle from a standing stop and run it to red line and see what happens in each gear but we will leave out overdrive, lets say 1st -3rd.

ooooooooh.............. a little different like WTF is going on, why is it running so badly...???

I've always been an NGK guy myself. Currently running 4306 , 5 on heat. And 44 gap. Thinking I might try the champs at 42 next time I pull plugs.
I'm thinking heat range changes would be more noticeable difference than plug type changes. ..if that makes sense. ..

I guess what I'm trying to say is maybe you would notice a heat range change more than you would be able to notice a difference from platinum to double platinum? If you jumped more than just 1 or 2 on heat, but y would you do that anyway lol ??
