Nothing to dislike. After learning the “hack†on how to install plugs into a Mercury Optimax V6 engine, I removed all 6 and installed all new one in around an hour, having never attempting this before.

I needed to replace my spark plugs on my Merc Pro XS. Plugs worked great. No complaints.

Yes, they're quite expensive for what they are. Requires gapping to 0.042-0.045, without damaging or even touching tip. Bit of a pain.But, way less painful than using an (un)equal plug from another manufacturer shown in cross reference guide, and then Melting
