looks like youre running lean..and one of your o rings is gone if there is oil on the plug...has your car been running poorly?

 

the white tips definitely look like a lean condition... but, 17k on plugs running the boost levels you have been is a bit harsh... i am set on changing mine at 10k or below... especially since i'm running 2 step colder plugs... are you're 1 step colder? remember, they're more susceptible to fouling due to the lesser spark...

EDIT - the more i look at the plugs, the more i see just normal fouling and corrosion from harsh use... if were truly lean, the ceramics would be white, as well...

 

+1 17K on same plugs I would def rec doing it more often but yea there fcked up

 

No wideband A/F gauge?

I know the car isnt running lean.. The plugs are really black.. That last pic is pretty misleading..

 

No defi wideband = none in my z....

 

= I have no idea what my A/F is which isn't good and leaves you reading tea leafs to figure out what is going on.

Innovate DB9 standalone = $279.

JET

 

I would look into that.. Just dont have the time and no shops near me to install this..

 

define "soaked in oil" - I don't see oil deposits in those pics. Don't count the threads

Looks to me like your plugs are a bit on the cold side, or your not that hard on the car...but that should be fine

 

Thanks!! Well one of the plugs had alot of oil but i wiped it down..

 

It seems you can forget the Innovate. Everyone around here can't seem to get one to work more that 24 hours. And Innovate is no help at all. I'm think of going AEM. What other options do I have? Don't say Fcon.

 

What kind of gaps are you guys running with the 1 step colder copper plugs?

 

Get the Tuner Reg wideband from Turbo XS. If your running the UTEC it will interface and data log. You can run a display gauge off the UTEC. Contact Quadcam. He did this.

Here's a pic fo the gauge that I am using on the output port of the Turbo XS Tuner. My Tuner is stufed up under my dashboard, so I use this gauge to see what is going on. But, when datalogging, my laptop interfaces drirectly to the Tuner/UTEC combo.

 

it's been discontinued for a long time now...maybe can find one used though

 

The gaps were set at .032 says NGK-R PLFR62 11 on the plug...... I dropped in some new iridiums one step colder with the gaps set at .038....

 

Whats the closest it looks to the chart????

Do you think this http://www.dansmc.com/Spark_Plugs/7.html

 

As far as the color of the plugs you are only going to see the way the car was running when it was last started. IE: It was last idling so it may show signs of it being a little lean. More damage to the plug would be a different case.
