Motor ~ 1.5L D15B7

So I pulled the sparks from the current civic I just bought and they looked rough no idea how long they been in there but from the looks quite awhile.

also seems like ash deposits are on one of the plugs pretty good.



well now that I have some new NGk's in there the car is noticeably better at accelerating and overall running, but only after 15 miles of driving on them I dunno if this is normal but the plug already looks like this.



can anyone tell me if this is normal? and what could be causing it I'm thinking valves maybe or maybe checking out the injectors for crap in them because I replaced the fuel filter recently and it had quite a bit of crap in it.

 

awesome to see a reply! thank you for the help and sadly I forgot to pick the anti-seize up when I was at the parts store as I was headed to work worried about being late, I'm picking some up tomorrow along with an AMMCO visit to see how my transmission is doing, and I double checked the gap on the new sparks after adjusting to .044

Thanks Tomcat39!

 

Better slap in some NGK wires while you're at it. 40 dollars shipped on ebay. Got em in my ej1, and they are hella clean.





And slap in a new distributor cap and rotor while you're at it.
