Spark plugs

[acdc96]

I want to replace my NGK sparkplugs with E3 Diamond Fire sparkplugs.

My sparkplugs for my force 9.9Hp are:
Champion SP #: RL87Y
NGK: BPR6HS

My Sparkplugs for my Yamaha 2HP are:
Ngk: B5HS
Champion: L9J or L10
AC: 45F / M45FF / 46F
Champion: L90C
Ngk: BR5HS

Re: Spark plugs

What is it you are expecting from these plugs, other than a lighter wallet?
