Spark Plugs - What & When ??Shiv??
Spark Plugs - What & When ??Shiv??
Shiv, anyone
I'll soon be running a stage 1 on a 93 Octane map, and I'm going to the dyno day in May to get a custom tune......
I was thinking of putting in a Walbro pump as well, but
1) What kind of plugs should I use?
2) And how often should I change them?

We've been using the NGK's we sell here on all of our cars, they work great. If you want part # it is: 5422 BR8ES
I wouldn't say there is any real answer to changing the spark plugs out. You can follow the manufacturer's reccommendation, however these plugs aren't meant for a crazy long life like some of the aftermarket plugs are. If you plan on doing track days, or just drive your car hard in general, I'd check the plugs every once and awhile to see how they're holding up.

smog,
from what i understand, if the ceramic portion of the plug is black, you are running too rich. if it is white, you are running too lean. if its a little tan, then youre doing ok

Something I don't understand
When I changed my plug to the step colder per Vishnu the center of the plug was off-white and the bottom rim where the thread is was blacker then black. Now from what you guys have said that mean that I am running lean but my EGT gauge does not show a lean condition at all. Yes, I have mad sure that the EGT sensor was installed correctly and the sensor is not bad. But I hardly get over 600c on my EGT gauge, even with hard pulls.

Stock plugs are the irridium 7's, 1 range colder are the one's Vishnu sells are the NGK BPR8's, it is IMO not good to "read plugs" these days as a correct running car does not always display light brown/tan plugs...best way to see how the car is running...wide band o2!!!
