Champion or MC plugs
 

Hey guys, my truck just hit 200k and I'm doing a a fluid change as well as all fingers and spark plugs. I was wondering which plugs to put in it. I know the mc will be fine but I was wondering the pros and cons of the champions. I know I've heard of them fouling out early. Is that still a problem with the champions? Thanks

Changing all fluids and filters*

Motorcraft SP-515 is the ONLY choice in my opinion.

Just about anything but Champions IMO

Motorcraft SP-515

Yep, stick with MC SP-515

I've had my Champions in for about 100,000 KM (60,000 miles). Not a single misfire. I'd say they are great when you get a good batch of them. I know a lot of people have had bad batches though...

I am getting ready to swap my plugs again. It's nice to know the Champions won't snap off, but I am going back to motorcrafts just to see if there is any difference in the butt dyno. Likely not, but maybe I might notice some MPG or something.

Thanks guys, I'm just going with the motorcrafts. I'm a firm believer in using the oem parts that were made for the truck.

Then why did you even ask....

Because I was still curious about the champions plugs!
