Spark Plugs - best brands?

[NFA]

Going to replace my spark plugs, any suggestions on the best brands out there? It's a 120HP, early 90s Force, thanks!

Force is owned by chrysler I believe..And chryslers LOVE Champion Plugs...So I would suggest them

The only thing I put Champions in is a lawn mower.

NGK works, and is the major plug I sell.

I have NGKs in it right now, and they worked well last season. Going to go with them I think.

Thanks!

My 2c, I have only used Champion since I owned my Force 125. Didn't have to change the plugs all last season. Ran great. Took the boat out the first time this season, did a de-carb, and it still was running like a sewing machine. THEN, I decided to change the plugs anyway. I bought some NGK plugs to try and I,m not impressed with them. Seems fine at WOT but idle in no wake zone, motor shakes like crazy. I'm putting Champions back in to see the difference. I will report back if it don't rain today.
(I hope I havn't developed other problems)
