WHat spark plugs do you run?

[bigmanjbmopar]

Looking for a change, been running the champion race plugs C63 series but after finding a couple of cracked insulators I think I may be switching brands.

What do you guys run? daily drivers, street rods.

edelbrock heads/street car i just go to walmart and pick up some autolite 3924's or 3926's. simple, cheap and no issues.

Ngk

I had the NGK fr4 before I switched to the champion race plugs, interesting thing about the NGK's the resistor on those was at 5.3k ohms vs a straight non resistor plug with metered out dam near a dead short. (which is good). what part number you have rebel?

Thos auto lights work fine no issues with heat?

Had champion.......now use ngk

N G K's.

Ok, going to go back to the NGK's picking up these from Jegs, free shipping anything over $30 today

R5671A-7 - NGK Racing Spark Plugs non resistor so direct boom hoping these do as they say and help out with the burn with that v groove deal.


Here is NGK's plug index.

Every since my motorcross days I've ran NGK's.

Autolite always and forever...

I used Beru when my dad got them for me from the dealership he was a mechanic at, after that I use NGK. Tried a lot - Autolite worked well for me, Champion were the worst no matter what car I used them in.



These would be just fine on a Panther Pink car.

Autolite and NGK and both have worked good for me. Ron

 

[65 Coronet]

NGK for me.

 

[lewtot184]

buy the most expensive platinum/iridium or whatever plug you can find and then buy some cheap autolite 3924's and do an ohm check on them both. i'd be curious what the difference is.

 

[bigmanjbmopar]

Lol all my coin went into the Evans coolant redo I'll trust you on the autolites. I had fouling issues last time I ran the ngk fr4's but turned out it was the pcv putting too much oil into the mix. Switched to the champs for a hotter burn, but now it should be ok with any decent plug we shall see!

Street driven beat up old 383 RR: something non-resistor like Accel 134, Champion J12YC or J14YC. If resistor is all I can get then Autolite 86. They all work about the same but the tach doesn't go wild with the non-resistor.

nobody has wasted more money and time on spark plugs and ignition gadgets than me.
