dont remember how many miles are on the plugs, maybe about 2 or 3 oil changes worth
ngk 6097's - BKR7E , stock gsr turbo 9psi

just wanting to know if they are sparking well , and etc

plugs are pulled in cylinder order 4 - 3 - 2 - 1

 

2 and 3 are running hottest, overall they look fine for the mostpart. Inspecting plugs can't really be done this way though. You really need a light, and magnifying glass to look down inside and inspect for any aluminum flakes or specks. At a quick glance they look fine.

Like I said, only thing I see is the heat in 2 and 3...getting a tad high. #4 might have something small happening, could be running cooler therefore not cleaning itself as well, hard to say.

 

did you pull them right after a wot run?

 

no i just pulled them after driving around,
i also forgot to mention, my car was putterin/missfiring thru out some of the rpm's, it never did it untill today, like i would rev up and it would hesitate to reach redline after lik 5k rpm in certain area's, thats why i changed the plugs, and it was fine after that

would gettin some colder plugs make it not run so hot , such as a BK6RE, or is there something else i should try

 

Colder would be 8s

 

okay, i havent dealt with colder plugs for a while, forgot, thanks

 

Yeah, you wanna see the heat only going about half to two thirds of the way up the threads. The 2 and 3 have heat way up top, which means they are getting close to overwhelmed and the ground strap could be glowing red and causing pre-ignition.

Also, don't forget to close up your gap a little unless your running a higher output ignition system...something with the power to jump the gap under higher cylinder pressure.

 

alrite thanks guys

so heres what i plan on doing now, run some BKR8E's and gap them at .030"

 

I dont think 8s would be good for your setup.. BKR7Es FTW on a stock 9psi setup

mine are gapped to .026 and it runs awesome

 

let us know how it turns out, pull them again and take pictures.

 

octane booster city I'm assuming?

 

dfw, 93 octane, going to regap plugs soon, and see if theres any difference

 

Since when are 7's the FTMFW plugs to use. He's running a 1.8 GSR, more displacement and more cam than a B16, and he didn't mention the turbo. Regardless, 9psi doesn't mean dick, his motor wants what it wants.

Based on your current state of tune, two plugs are running pretty hot is all I'm saying. You could close the gaps down...maybe be fine. Maybe your A/F's are a little leaner than B16 boy up there and your combustion temps are hotter. Either way, use the plug that the threads tell you to use, not what some unwritten universal "9psi means 7's FTW" rule says.

In my opinion it's better to go one step colder, and check those out to make a good judgement. You ring a stock piston it's gonna crack. Get another set of plugs, and run them for a bit. See what the motor wants, then run it.
