Ruthenium spark plugs

Postby Jesda » Tue May 04, 2021 3:35 pm

I'm about to buy plugs for the Mazder. Anyone running these? Who/what are they for?

NGK claims 2X the life of Iridium and better oxidation resistance, which I'll buy. There are some ruthenium alloys that are off the chart for both melting point and corrosion resistance. NGK also claims "high ignitability", which I'm not sure I buy. The way Nissans stubbornly refuse to fire when flooded, maybe they're more resistant to flooding and that would be nice. That one goes in the "we'll see" column. I think the bottom line is, if you're ride has insanely hard-to-change plugs then they're probably worth the difference. Otherwise, Iridiums are already good for 100K.

My thoughts exactly. I actually run NGK coppers in my 240 cos they are so easy to change. I slap new ones in every 2-3 years and never have an issue. They still look more or less fine when I pull them.
But yeah, if I had a subaru or H-something, you better believe I'd be putting in the longest lasting s*** I could find.

Just heard of that ruthenium spark plugs. I'd be curious if that will be better than NGK.

The rutheniums are NGK's. Just pricey ones.

Hmmm.,
My interest is piqued.
I am at 170k, was told my plugs "look good", so they been changed once.
I intend to run this VK56DE forever and a day, so maybe 200k sparkplugs would make sense.

I ran these plugs on the 16 Rogue and will be running these same types of plugs on my 17 MDX and had no issues.
