Mine had 3 kinds of spark plugs in it haha. Ac delco's, bosche, autolite, I think that was the three, non the less there was 3. Now there all the same though.

mine had the same plugs, but 8mm wires on the driver's, and 7mm on the pass. They're all new plugs and 8mm wires now.

oh and time wise, took me and my dad bout 6 hours for plugs and wires on both sides, still have an msd coil to put on.

Lot faster than that. Four of mine were missing after 12k.

be carefull also lots of shops are crooks and will charge you like 250 to change them and leave plug #2 cause its such a pita and still charge you for it.

when I had stock manifolds it took 90 min to change 7 of the plugs and about 3 hours to get #2 done


now it takes 20 min todo all 8 with the race motor :P
