I also use these plugs in my camaro, never had a problem with them.

 

NGK Iriduim IX w/ Mopar Performance Wires

 

Thanks to all of you who posted information about Bosch platinum plugs. I can’t seem to locate the tread where I was warned about using platinum plugs, so I’ll just tag on to this one. I’ve been using Bosch Platinum plugs for years in my 3.3L Plymouth Voyager with no issues. I can get 100K miles out of them easily. The Neon is a different story, or so I’ve read with is “waste spark system” ignition. After 34K miles these Bosch plugs eroded just like you guys said they would; notice the missing center electrode. The second picture is what it should look like. I just installed the Vpower NGKs. We’ll keep you posted on their performance.

I have the v powers with msd wires.

 

The plugs are supposed to be changed every 30K miles anyways

 

hey was up man im runnin my 5speed 2004 SXT Neon with the NGK iridium IX sparkin with a MSD coil and 8.5mm MSD wires .... well for me it works great .... ive experiance quicker throttle respond and acceleration u should try the NGK iridium IX if u want better respon and more better fuel burn.... out of ur neon try emm with some aftermarket wires and coil like mine ....

 

Do you really have to change your plugs at 30thousand miles Im way over that last time I changed mine . shes still running nicely just took a trip 700 miles aways and my sxt got 36 mpg and she has over 178,000 miles on her. So the plugs must not be that bad.

 

You don't have to do anything you don't want to do. That is what the service and owner's manual says to do. I do it because they are cheap (OEM plugs) and at about 30,000 miles, the center electrode has begun to round. They could go longer I'm sure, but the amount I drive, even an extra MPG or two is worth the $10 plug change.

 

You are correct sir about what the recommended service interval is with the standard OEM plugs, but platinum plugs are supposed to last 100K.

 

Some are rated for 100,000 miles, but not all of them. Just because "platinum" is stamped on the package, doesn't mean you can toss them in and forget about them for 100K. OEM DoublePlatinum and OEM Iridium plugs can be rated for about that long though. Newer Toyota/Lexus vehicles use a Denso OEM Iridium plug that is rated for 120,000 miles. Regular, single platinum plugs don't fall into that category.

Here's some more about spark plug life. According to Autolite, you aren't supposed to use a regular copper core spark plug, or a "single" platinum spark plug in waste-spark ignition systems. What does Dodge use? A regular copper core plug. Denso recommends not running their Iridium plugs for more than 30,000 miles. Autolite and NGK say to change the plugs at the manufacturers recommendations.
