Champion QL77's but look down the page a bit for a post titled "What plugs to run" The search function is also a wonderful thing

That link is about crossflows. QL77JC4 is the resistor plug, L77JC4 is the non resistor. You'll have many people tell you to run the BR8HS NGK, but I like the Champions.

That year model should have QL78yc plugs

Hey Al, what year did they change?

**racer** · 12-05-2007, 01:46 PM

The first closed deck blocks had ql77jc4 (1993) The 94 on now call for the 78YC plugs, remember the original 93 had a smaller chamber in the head.

93s had a smaller chamber then 94s?

I originally ran the 78YC in my 2000 OMC but I switched to the 77jc4 cause I had a whole bunch laying around and didin't notice a difference. Whenever I change 'em I look for the 78YC but if I can get the 77JC4 cheaper I just use those.

i was told the 77s are cooler so their better to run.
