I usually use NGK because they stay close to factory spec. This time around I went NGK V-Power. I've seen where people on other forums swear by Champion Copper plugs. What's everyone's opinion?

I'm actually asking because my truck has been doing some weird stuff for a while now. It will seem to jerk while at highway speeds. I'm not getting a misfire CEL but I've read where the wrong plugs can cause this same thing.

I buy NGK or AC-Delco, nothing else. I've just had to many champions crack and/or fall apart on my lawn equipment. they're decent enough plugs that its OEM for briggs and stratton engines, but I just don't like them.

So apparently another option people seem to live is Autolite 3923. I wonder how those do compared to the v-Powers I have.

i ran auto lite 3923 plugs for a long time. No complaints. I was told to get them because of my sct tuner


They were good plugs. Didnt last very long tho..i replaced them with comparable NGK plugs.

I never ran champion copper plugs, but alot of people like them

I heard champion makes or did make "truck plugs".


If your looking for a good plug the auto lite 3923 were great

My NGK now (hotter or colder im not sure) with summit 8mm wires make my 318 run so smooth and quiet.

Cant go wrong with either of these!!


I do run NGK plugs in everything tho. My 69 charger, Lawnmower, golf cart, Honda trail 70s etc. A old mechanic told me that ngk plugs keep themselves clean the longest.....which i would believe as i never replaced one due to fouling

AL 3923 are decent but most guys run NGK BKR6E. Both are 1 step colder than factory and go great with tuning. Without tuning I would run factory heat range, AL 3924 or NGK BKR5E. I run the 6E's

Never had any issues with Champion RC12YC but this time around, I went with NGK BKR6E as a result of my tune.

I ran nothing but NGK in my Hondas back in the day and never had a problem.
