damn the cross indentions are gone!@

 

They look like they are burning good to me .. but thats alot of build up for only 1700 miles. Is it cause its a new rebuild? ... could that be 'break in' build-up?

 

Haha ya they are Nippon Denso plugs .. the NGK's have the cross cuts on them.

 

they look good to me

 

new motors reak havoc on plugs
take a wire brush to get them clean again but they look ok
mine look like that after about 2k i just clean them and they are good as new

 

Ya, they don't look horrible .. but on my N/A I can pull the plugs after 10k miles and they are clean enough to eat off of. Thats the only thing I have to go by (Rotary Wise) is this normal -2k wear for a TII? the burn looks good.. just the build-up looks a bit exsessive.

 

NGK's also have some like that too (w/o cross cuts) Looks good, maybe a hair rich

 

look like to me they are very normal!
