Since the stock SRT8 plugs are platinum, what now?Anything but a bosh platnium triple fire,coss fire, mis fire etc! Factory plugs are about the best. Only other ones i would use other wise would be a NGK

While I have no experience in the Hemi sparkplug area, I have used the Bosch Platinum plus 4's across DOZENS of platforms, imported and domestic, with great success since their introduction. V8, V6, inline 4, boat, even in my street killer roller motor, not a single bad experience, none. I suppose you hate Dexcool, too.
Members here have had success in 5.7's with Bosch plugs. It would be great if you would flag that post with an "In my opinion".
Factory plugs are CHEAP. That's how they're chosen, by price.
Hmmm, I remember someone just like you raving about putting Bosch in my fleet 3500 Savana's. They were wrong, too. Do you know that if I put Mobil 1 in one of my flat tappet lifter cars it can destroy the cam/lifters? I won't keep a bottle of that crap in my shop! And Dexcool can destroy your engine! Except mine, which run forever on it! One has 300000 miles!I wouldnt run a bosh platnium plus 4 in my lawn mower! Second factory plugs are not cheap? Where do you get this information?I do this for a living.
Perhaps your lawn mower wouldn't care? I didn't think we were talking about lawn mowers. And if you think costs don't rule the auto industry you are truly mistaken! Most factory parts are better engineered than aftermarket, but only those made "in house". The subcontracted parts are bought from the lowest bidder in most cases.
I also do this "for a living". I am formerly NIASE certified and have worked in a dealership, but I also maintain my own fleet of service trucks and personal vehicles. Bought my first car in 1972, back when plugs mattered!
Chrysler likes champion or NGK period! Bosh platnium,A/C delco rapid fires,etc are garbage!!!!! Snake oil!Stay away! You are probably running a tornado in your intake also and going to tell me you picked up 2 mpg and 30hp.
Wow! We went a long way off topic there. Your opinions are your own. All I asked you to do is label it as opinion. I hope the insults help you to express yourself, but the typewritten word is a difficult medium for many.
I dont have a GM nor do i have any experiance with Dexcool. I run Factory mopar fluids and filters except for the oil which is Mobil 1.
LOL your a chrysler tech correct? And if so i know you've had to come across secondary ignition problems caused by Bosh,autolite or other plugs.Seems to me these spark plug threads have the potential to rival the oil threads...haha. Kinda reminds me of this thread - http://www.300cforums.com/forums/general-discussion/19740-do-platnium-plugs-make-difference.html.
Once again it's just one small word. Change the "caused" out for a "maybe"? The plugs were blamed for the problem, but that's hardly proof. I heard the same thing from GMC techs about Bosch plugs!LOL your a chrysler tech correct?

We have Mr. Incredible running platinum plus 2's and Landonelf running Bosch platinums as well, both with NO PROBLEMS! Seems like they do work after all.
I hate the "I heard" stories. I once heard that dealerships were the WORST place to get work done on a car. Should I quote that as fact? Nope. I will give you credit for trying to inform us of what you believe to be a threat, but we may not need saving.
Let me tell you, the fact that you are in a stealership offers no credibility to most owners. That is the number one place to get misinformed!
Back to the OP's original question of what plugs are recommended for his 300C! I think the overwhelmng concensus of all the various threads in the past has been to use the OEM replacements. The old thread I linked to above seems for the most part to confirm this. There are many others as well. I don't even think there's anything to prove performance gains or gas savings using iridium plugs. To me it doesn't make a whole lot of sense to have a bigger spark if all the gas is being burned effectively as it is with the copper core plugs.I have been using the NGK Iridiums. I have seen no performance difference and little gas MPG gains. At $7 per plug ----I won't do it again. Stock plugs for me in the future!!!!
