Do these look normal - BAD - OK or what?

They are NGK BR7EFs that have been in for about 6 months. I want to see 12s at the track tomorrow night, so I figured fresh plugs might help. Anything I should be worried about with what you see here?

BTW - the second time around on the plug swap was a relative breeze - 1hr 15 minutes compared to 2 hrs 24 minutes last time (1st time) back in June.







Thanks all,
Herb

 

They look good to me. Nice tan look on all of them and no speckles from detonation. Good luck on the 12's!!

Zach

 

they look good. I can get my plug changes down to half an hour if I don't have to gap them.

First time took me like 2 hours

 

your still a rookie...
Hour and 15 minutes ....what are you doing taking three 15 minute breaks

Plugs look good

 

I hope my NGK BR7EFs look that good when I get around to changing them. Oh, btw, mine have been in for 58,800 miles now!

Thanks for the replies guys.

I installed my Wideband O2 gauge and have been playing with the setup on it. On the past couple of 1/4 miles passes, I've seen the warning light flicker. I wanted to make sure the light was on due to my settings - not due to running too lean. I figured the plugs would surely show my 'past indiscretions' of the throttle if I ran lean at any point. I've played with the smooting and the RPM settong for the warning light, so I'll see tonight.

The truck ;feels' better with new plugs , but the calibration on my buttdyno is out of date.

Red - you gotta look at my TREND.... 2:45 first time, 1:15 second time. That's almost a 50% improvement - so next time, its 38 minutes for sure....and i'm

I'm at work and dont have good graphic's
But I'd swear I see green on the tips ???

Green = Lean = Detonation
(I'll look when I get home, It could be the graphics on this puter)


But WOW on the time it took
I did mine for the 3rd time Sat, @ 1-1/2 hours for 7
Then it got dark, Sun Morning it took @ 3 hours to get the
last one on the Drivers Side _$@^)$@^)$@%($%@$@$
NEVER HAD A PROB with that one before.
ALL THE TIME was spent on taken the coil bolt out and getting it back in, (THE SOB CROSS THREADED) not bad, but it took a couple of hours of playing to be able to get it back in hand tight. The 8th plug itself took minutes to do.

I really got to get a 7mm Swival Socket
_@$^)@$^)@$^)@$^)@$^)@$^@)$

My 1st time Took @ 2-1/2 hours
the 2nd a lilttle quicker
But then again, I have to stop and tune up OFTEN



EDIT

BRO
YOU HAVE GREEN TIPS ALLRIGHT, AND THAT IS NOT GOOD

Give me a minute

 

Of course yours ARE NOT this green YET
BUT THEY WILL BE UNLESS YOU DO SOMETHING
BTW
I checked mine ONE WEEK earlier and they looked perfect


Back in the summer of 02 when that happen, I put Denso
IT-22's in, here they are as of Saturday, 3 racing seasons later,
2 WITH NITROUS. NO GREEN (and this is RIGHT AFTER (2) 11 sec Nitrous Runs)



I am not trying to scare you,
You ARE NOT going to blow up
It's not TOO BAD
BUT they are clearly green (light green, but green all the same) Since you are already 2 zones cooler than stock, I'd say
RICHEN IT UP, and you'll be fine ; o )

 

Dan, I am going to install mine as soon as I get my heads back. Did you like the BR7's?

What about driveability?

Sorry to hi jack you thread Herb!

Suavy

 

well, it's just my opinion, and Rob already beat me to it, but I was going to say that IMHO they look like they might be a little LEAN.

not only the green, but the WHITE porcelain. the porcelain should be TAN or light Grey, but probably not WHITE. you've got half tan half white. a wideband a/f recording might be in order.

maybe I'm wrong, but it might be worth a closer look.

but while we are on the subject...

Rob02!



that glossy or "GLAZED" look on your plugs is not from one too many tokes, you appear to have the incorrect heat range for your nitrous application. looks to me like you could use a colder plug.

some plug reading info here:

Autolite plug reading chart

NGK

I'm no expert though, I've got plenty of plug problems of my own. so take my opinion with however many grains of salt you wish.

good luck.

chris

 

Thanks guys,

Rob - on your plugs, how close to the photo do they look in real life? What I mean by that is, my plugs are actually a few shades darker live. The flash tends to wash out the colors and artificially 'brighten' the picture. The white areas in the photos look like a new porcelain color, but they are more like a dull ivory in reality. The green tips are actually more of a dusty tanish gray, like the color seen on the top threads in the pic (about 4-5 threads down from the electrode).

Maybe its me trying to wish the problem away, but the photos seem to make the plugs look more 'severe' that real life. Was that the case with your plugs as well?

Is this a concern that should keep me from running tonight?!?!

Thanks,
Herb

 

Suavy: Yes, I like them.......58,800 miles worth

Yes, they produce a mild 'miss-fire' at idle but above 1,100 rpms or so they smooth right out. That 'miss' at idle-only has never been a problem and it runs smooth at WOT. I gapped mine at 0.040".

Btw, I get from 14-15 mpg too with them.

Dan

 

Yes I agree a picture IS VERY HARD to tell TRUE color
as I said, they're clearly not as bad as mine were when
I had the melt down.

Chris,
I was suppose to trade Johnny those Plugs for one Range Colder
(to the Non Projectile type Denso's). (which would put me 3 ranges colder than stock). He offered to send them right out when I called him Saturday, but since my Truck was missing and I already had these, and it was a WARM SUNNY DAY, I figured ah what the hell I got 3 racing seasons out of them

I will now buy that other set from Johnny and keep them as spares for next time, I ALWAYS KEEP SPARES.
As for my Color, As Herb said the Pic's DO make them look a bit differant, I have them in my hands right now, and Bro I got to tell you, THEY LOOK PERFECT. A beautiful Brownish color, (not Red) (not too White), and every entire one looks identicle.

The bad part is JDM day was the first EVER trip down the 1320 with my new Chip Master Revolution Chip (and new Programs)
so I DO now have to keep an eye on the plugs and read them in a while to see what they are doing. This will be an advantage with new plugs and no more racing this season, I'll get a great idea when I check some in the spring BEFORE racing

 

Herb,
let me know if you want another truck to practice getting your time down. I need new plugs.

 

Come on now Scott - then I'd be stealing YOUR time improvements. That just wouldn't be right!

Let me know when your ready for it and I'll help you with them. Their really not bad at all. Number 7 is a bogger with the fuel regulator in the way, but for the most part, its all in the right tools. I've got the 'right' tool setup for the job and can bring them along when your ready. I'd suggest checking the primary and secondary resistance of each coil pack when your that far in.

You going to the SVTOA meeting Friday night?

If so, we can talk more about it then or at Biff's afterwards.

If not call me at 210-287-4020 and we can set something up.

Later,
Herb
