Spark plugs....

(Click here to view the original thread with full colors/images)

I'm going to do my tune up this weekend... is there such thing as performance plugs for the mark 8? What are the best performance plugs that i can get and where can I get them?

Autolite 764 spark plugs is what most recommend. Most people will also advise against the platimum plugs.

Depends on Mods. Some guys go a step colder, things like that. Me, I would rather change them out more frequently and the Autolites for a $1/pc at WallyMart are hard to beat.

I run the Lightning plugs with the 9MM Ford Racing Wires. The part number for the Lightning plugs (which are 2 steps colder) is AWSFA-12C. I got them from Max at 5 Star Ford (both the plugs and wires) 1-800-866-1520 ext. 236 and you can NOT beat his prices. The plugs normally were $3.59 each and I got them for WAY under half and the wires are like $140 and I got them for $105. The crappy Auto Zone 8MM wires are more than that.

well as far as the platnum plugs i have the bosch plat 4 and have not had a problem with them.(unless thats why I'm so slow at the track?) and the 9mm ford raceing wires vary good , got mine from a performance store down here cuz i cant wait for wires while the car was broken, i got them 120.

I run the Autolite 764 coppers gapped at .048 in ALL my Marks as well as customers too. Including the Superchrged SuperMark.

My 2nd gen wouldn't start in cold weather with the bosch plugs. Switched them out with the Autolites and bingo. Starts before I turn the key.

I run the single electrode Bosch platinums, .048 on the gap. I've never had a problem with them.

I just put in the NGK iridium plugs and it seems to be running great so far.
