I am running these for 15 Months, the first one looks like it has the fish sickness which they call "ick"

The white color thing on the plug do not seems to be burning correctly

[Streethondas]

My 3rd cylinder plug is always lean..

 

[abunai888]

new plugs with almost 900km on them with my old tune/tuner/set up.
pulled these after normal driving between 2000-3500rpms

What experts think on these ??

imo there is some kind of detonation-preignition and these are running rich ??

 

[vteclover]

Plugs that came out a oem ek4 with 48.000 km.
Don't know if these where the first plugs or that these where the second set.(what do you guys think??)

Everything else looks good to me

Knock appears in the forms of black dots on the porselan iirc.

 

[abunai888]

''The porcelain shows up pre-ignition and detonation (timing/octane). It will not accurately reveal jetting/air/fuel ratios. To look for the first/beginning signs of detonation, search the white porcelain for tiny black specks or shiny specks of aluminum that have fused to the porcelain. When detonation occurs, part of the air/fuel mixture explodes instead of burning, the explosion is heard as a "metallic knock", this audible knock is the result of a sound shock-wave...''

Reading Spark Plugs Correctly

so there can be black spots or shiny spots too.

White plugs are usually running too lean, could be caused by a vacuum leak also.

It could also be the wrong heat range plugs

How to read spark plugs

interesting post i found.

If you want to check the plugs at WOT then shut the engine off when your at the top of the rev range, or there is no point checking them, as the ECU is in closed loop mode.
Not really much point checking them when the engine has just idled?

Should you still do this even if the plugs have a few thousand miles on them at various rev ranges?
