I found this link and its a pretty good site to read up on reading spark plugs. If you dont know what reading spark plugs is, its when you take a plug out after running the motor at WOT and you can tell how its running by the way the plug looks and whats on it. It can give you an idea if the motor is rich,lean,detonating,etc.... its a cool peice of knowledge to have and i use it to read my plugs on my car after a hrd nitrous run to make sure things are good.

wow no one found this useful???

 

i just dont want to read it now, lol

 

I will after I get my rear end built and a nitrous system installed.

 

Good post Spike, that will definately be useful since i will be putting nitrous in stauday, just baught Autolite 103's today and gapped them to .035

 

This should be a sticky. I found it very informative. I learned a little more than I knew about plugs and I think it would be very helpful for people that are running FI or just wanna check theyre plugs.....

 

Sticky This Mother!!!

 

I agree 100%

thought maybe it would help

 

I should really check my plugs more often. I just hate the idea or pulling them out then putting them back in...lol...lazy I know

 

nice post.
It has officially been stickyfied...

 

i dont alwyas pull all of them out, but when i do it i will pull a few random ones. Today i just did one just to see how it was running.

 

Does this apply to individual coil spark plugs as well? Is that what it's called?

 

It applys to any spark plug that is being used. its just a way to see how the car is running IE lean,rich, detonation etc...

 

good post i found it veyy usefull for dialing in my n20 system

 

i dont wish to become mechanic at all so i dont intend to know anything about spark plugs at all
