I'm at 23K and have a high-speed miss.

So then, Probably Platinum plugs it is! Now which platinum to get? Cheapo Bosch at like $2 a plug, Bosch Platinum +4, NGK Platinum's?
#16 of 23 chrysler has always been partial to champions

I suppose they fought hard to get in there because DC has never owned a plug company. I thought they used to use Prestolite a long number of years ago, but it was champions by the 60s.

For applications that use copper plugs as OEM I've had good luck with Bosch Platinum's, especially for engines with high compression pressures like you'd have when your PT's turbo is spooled up.
#18 of 23 I've used Bosch Platinums

in my '87 Corolla FX-16 and 4 Mustang GTs - I like the way they burn.
Now, all I have to do is find them for my car - Pep Boys, Autozone, Napa, etc - NO ONE has plugs for this thing yet.
#20 of 23 spin one out and let us know, or check your owners manual recommendation

just to check one online catalog, autolite 3923 series plugs will fit the V6 engine, 3.7 Liter, designated engine K by dodge.
we could play that game all day with each brand and each engine.

I have a PT with a 2.4 (4cyl) turbo...
#22 of 23 no, there was an earlier post asking about ram 1500 plugs
Sep 18, 2003 (6:52 pm)
that has now been deleted. asking what his truck used.
while DCX/chrysler usually has been using champions, they could have used anything in any particular car, especially if the engine was from another maker. so it's really hard to tell.
you can be sure a ford comes with motorcrafts in it (unless maybe you had a yamaha-tweaked probe or something, it might have NGKs standard), and I would be shocked to see standard plugs in a GM that didn't come from AC Delco. but mopars don't have ownership in a plug outfit, and they could take whatever comes along if they wanted to.

I can remember when a set of spark plugs were good for about 12,000 miles. I remember what a difference a new set of plugs would make!
And, I remember points too.
I picked up a couple of spark plugs in our shop the other day that had come out of an Odyssey with 90,000 miles. Original plugs and they still looked fine.
As far as brand. I was always taught by the old masters in the business to use what came with the car from the factory and to NEVER, EVER use Champions!
