Good luck getting the old ones out

 

check sparkplugs.com for prices when you do find the ones you want

 

I bought a set of champions, but didn't like the looks of them... Think I would go with brisk racing's non- platinum one piece plugs and just change them more often, they look to be well made, just not platinum tipped.
Be sure to check the TSB on removing the plugs, breaking off the plugs is not something I'm looking forward to, that's why I still haven't changed mine yet. I put up pics a couple yrs ago of the champions, I really thought they looked like junk- one of the 8 wasn't even threaded as far as the rest...they're still in the box.

 

Ive used motorcraft,autolite and brisk, and the best plugs so far are the Brisk
Btw Autolite suck,motorcraft as long you change them frequently there ok and Brisk hold up the best so far

 

Haven't been here in a while, but that's classic. Those **** things cost me a chunk of change after breaking 3 of them.
