Ok so I decided to check my spark plugs... and the tip where you gap it is grayish/white.... according to my search. That means I'm running lean.....and its grayish/white. on all spark plugs..... the thing is I have a 1998 hx swap d16y5... and its a lean burn motor.. and its swapped in legit running the correct ecu......... since I'm running this lean burn motor.. does that mean that its normal for my spark plugs to show grayish/white.?


a little more info the threads have a black stuff on it... but its not on the tip of the spark plug.. its just on the threads....... o yea i took pictures after i cleaned them so you may not see it clearly

UPDATE.... 2 plugs have very little oil on the washer portion of the plugs... JUST THE WASHER has oil on it

 

Light tan or grey is normal, your look black, either carbon.

Where do you see white?

 

The part where you gap it looks gray white.. then its black at the threads

 

Its white on the tip where u gap it.. but its black near the threads... I sea foamed the motor not too long ago... but jus through the gas tank

 

The second picture shows a little white on the tip where u gap. But the threads and circle part is black. So I have no clue what going on... I'm changing it soon though after I sea foam it

 

Jus went on ngk website. Looking at the chart, my spark plugs seems to be normal apparently... .. mayb slightly running rich..

 

Your spark plugs are perfectly normal, white means its running lean and is not good.

 

it was white/gray before i cleaned them... so they look a little better....

im running a lean burn y5 motor.... isnt it supposed to show lean since its a lean burn motor?

 

update... i have very little oil on the spark plug WASHER and washer alone... nothing else

 

Running lean and a lean burn motor are not the same things. Your plugs are fine. Move on.

 

They look okay to me, now that you have them out, might as well replace them. They don't cost more then a few bucks.
