I have a 65 Fury with a 383 and It has champion plugs in it, which I've never been a fan of. Is there any brand you've found that works best with the 383?

champion is the factory plug for mopar. that is what i run in my valiant.

Mr.4spd

The parts guy at my local Federated auto supply told me Champions used to be good, then they got really bad, and now they're back to being good. Perhaps your champions were made when they were bad? He told me NGK plugs were excellent. I then bought 4 cases of Champions, made in the USA.

CHAMPIONS are the plug of choice for Mopars. In my opinion they are the only plug for Mopars, NGK is a forgien car plug..But you know what they say about opinons there like as-holes everyone has one...Bill

I mean there is a whole science behind spark plugs and their optimum heat range, gap, etc... but, I have always heard that Champions just run better in Mopar. May have to buckle down and do the research online.

My personal experience is that it doesn't make much difference. I have run champion in my mopars and NGK in small engines particularly two stroke (lawn mowers, fourwheelers, dirt bikes etc..)

Just my two cents.

RacerHog

Champions are made in Mexico. Only thing in the champion from here is the Core. That's done in Ohio. Dam Shame too, I might add.......

I Like NGK GR4 myself.... Works for me......
Autolites work ok... Champion work ok....Bosch works ok... Ect...
I just have better luck with NGK lasting longer between tune-ups and the plug looks better when it comes out...
Just my 2 cents

Sorry Bob I kinda stole your tagline there...

I too have had real good luck with NGKs in Boats, Snowmobiles ,Dirt bikes etc... But Mopars like Champions if you go to the dealer and ask for plugs you will get champions with the mopar logo on the box...And what isnt made in Mexico Or China..It is a Damn shame!!!!! This country better get its head out of its as- before there is no country... But at least the government is back open whoopty doo....Bill

RacerHog

I Like the way they say (We kicked the can down the road)

That's it.....WTF
Keep it closed.....

RacerHog

Look Guy.... The spark plug interval for like a 2010 Dodge Ram 5.7 is recommended to replace @ 30,000 mile....

That just tells you something !!!!!!!!!!

pro-tech

Really then Im way over due and there are 16 of the mothers at at least 8 bucks a piece... sh-t I thought it was closer to 100,000 miles I have 40,000 so I thought I had some time... Mine is an 2003 do they require replacing at 30000 also or just 2010...Bill

RacerHog

Yes Bill 2003 5.7 Hemi is also 30,000 mile recommended replacement.

IF you go a long time with those.... You will have like an 0.080 gap...lol
And smoke the plug boot and the coil...And believe me it arks dam good..lol

pro-tech

Thanks Bob, Its funny as I was lying awake last night I was thinking you know I havent changed the plug in my truck ever. And thought its 10 year old and there aluminum heads I had better change them and put never sieze on them. No lie it blows my mind that you brought that up...I guess you really do have my back...LMAO...Bill

Skwerly

I've always gone Champions in my Mopars, too.

RacerHog

I still don't know or have the answer on why they never went to platinum.
Must be a Dealer thing....lol

Dave E

Change the plugs every 30k in a new Hemi? Wow that's outrageous!!! Why haven't they gone to 100k plugs.

pro-tech

Hey Bob, Just got back from Car Quest and the plugs are copper cored I thought they were platnium they are made inthe USA in MI. The plug number is 570 and@ $2 ea. So they are not what I thought or was told by the great parts guy at the dealership I worked for. I should of know when he fired back when I asked for plugs for my truck. "There platnium how many miles are on it". I hope they come out ok...Bill

RacerHog

Dave, Even Toyota Tacoma's 4.0 V-6's..... Every 36,000 it's recommended for replacement... And they are platinum...

Bill... I did say wrong... They are put together in Mich....
Now there could have been a change, But when I did a factory walk threw a few years ago, That was what it was. Cheaper to do it else ware...

I'm going to say you'll do 16 plugs...lol Those last two you will have some choice words for.

Mr.4spd

So Champions ARE made in the US? Do you have any idea how close I was to kicking my parts guy in the stones?

pro-tech

My guess as to why they are useing copper cored plugs instead of platinum is to either get the plugs out of the heads at a scheduled interval so the dont sieze in there Or to make service work for the techs in the dealerships...Look at the intervals of differential services 15,000 miles and its synthetic gear lube that to me is insane.. back in the day nobody serviced them...It is all a money making scheme...Bill

pro-tech

I wouldnt change them that often I would wait to 60,000 miles. In my truck the parts store had a platinum plug listed but it takes me 10 years to get 40,000 on my truck so I opted out and said I will have to replace them in a few years just to get them out any way so why spend the extra ...Bill

RacerHog

What you said is very true Bill..... I'm not sure that I have ever met anybody that dos'nt extend the service intervals....lol
That includes Me, But that how we learn...

pro-tech

Well I changed the plugs and it wasnt to bad about 1.5 hrs. The 2 under the brake booster were a little tight. I started on the hard side (Left Bank) so when I got to the Right Bank it was a cake walk. The plugs were worn from .045 to .070-.075 gap So not quite .080 gap but what a difference in the way it runs..I also cleaned the throttle body, it was quite dirty considering the way I change the oil...But over all pretty easy with the right tools but I also have done a few in my day so for some reason I didnt remember them not being platinum plug must of been a brain fart which gets more frequent the older I get.....Bill

Dave E

I am way out of me element here anyway... I don't usually keep a car long enough to put tires or brakes on it let alone plugs!

30+ cars since I was 16... I am 31 now.

RacerHog

Now Thats a sweet Deal......

RacerHog

Glad you got it done Homie!!! ..... Funny how they never miss a beat... Eh

Dave E

Technically my first car was an unrestored 1970 Challenger (the only one I still have) but the first car I actually drove was a 1980 Plymouth Horizon. I have had some real winners in my day.
