Hey does anyone know how to read or have any good links to sites that has pictures and tips on reading plugs and how they should look after nitrous passes.

I know what plugs should look like with normal n/a wear but what about nitrous, I pulled my plugs after about 20 passes and the electrode is worn is this normal

And how many passes can I look to get out of my new plugs on nitrous
ngk v-groove 1 step colder

I wondering the same thing. I just ordered some colder ngk's for when I step up to the 75 shot.

I got my plugs from r&s struass for 12bucks .. I could tell from the ground strap that the plugs were getting too hot, and the fuel mixture is ok alittle rich but was not sure about the electrode

Great link

agreed good link I even printed this out encase the link ever goes down
