spark plugs.... there a pain can someone help PICS INSIDE!

[SRiz]

ok well my engine check light went on.... got it checked it was multiple cylinder misfire the guy told me to get new spark plugs... theres a pic of what my spark plug looks like its prolly the stock one with 100k miles on it ..... ok well i got new ones ACDelco big mistake there for GM trucks uhhhhh damn advance auto ....ne way i sent those back and i need to get new plugs theres a pic of my old one seems like i might need a colder one i am gonna get the NGk not sure which one yet ....im running 14 psi prolly gonna go up in near future ne suggestions on what plug i should get the "6" or 7" one or should i just get stock ...and does it look bad from pic or just workn? ... ok also... i got new wires there too there Xacts they seem to work fine do you think i should bring those back soon or get new ones i had magnicore i have a pic of em is that good wires cause the guy at Advacned cut it open to show me how crappy it was and i think there worht like 80 bux!!!!!
ok well i have alot of ?'s in that rant if u can answer all or any please feel free!

It would be much easier to answer/read the questions in your 'rant', if you would simply use periods....

You will be fine with the stock heat range of spark plugs. Get the 6's.

i'm running 15psi and i had issues with the car studdering under full boost. So i changed the plugs and wires. I went with the NGK Bpr7es and magnacore wires and i haven't had any other studdering problems.

 

[jasoncitrano]

there is a thread out there somewhere about resistance levels of spark plug wires. Magnacore was up there as some of the worst wires out there!!

 

[SRiz]

ok new question... is Xcel any good should i use them in combination with the NGK plugs? i think imma get the 7's cause it had 6's in it and i was told it was too hot look at above pic does it look burnt do i need 7's?

that is the wire resistance thread. I don't know Turbo's very well but I think if you are running high boost then you should try colder plugs and lower reasistance wires. I have Accel wires on my NA and they are great. good luck.
PS. Accel's were cheaper than stock NGK repalcement wires.

I had the same problem as you, i changed spark plugs out 3 or 4 times and then i changed the wires to the accel ones with some autolite plugs and i havnt had a problem since. one thing about the accel wires is they are a few inches too long for the 2g so they dont fit under the spark plug cover to well.

Resistance of the conductor has no influence on the propagation of the ignition signal.
This kind of stuff is continually posted on this board by kids who flunked science.
The ignition pulse behaves as though it were a high frequency alternating curent signal and travels on the outside of the conductor. Usingthe results an ohm meter to make a qualitative judgement regarding ignition wires tells us that you do not understand the subject.

You guys need to know what you are talking about before you go online and sully another man's work.

OK!!!! heres my spark plug choises... PICK ONE.... Accell thundersports... magnacore 8.5... autolite 7 mm... Xact 7mm... or NGK oem replacement ... put in what IS the best ordering tonight!

I read through that entire thread and I don't think one person mentioned the fact that resistance of the wires doesn't make a difference in spark. If it only takes 2000v(made up number) to jump the spark plug gap for the compression and a/f ratio in that engine, it won't make a lick of difference how much voltage your ignition system can deliver because the spark will jump the gap at 2000v and will burn just the same. I would be more concerned with quality insulation and a wire that will last.
That plug in the pic looks like it's platinum tip and doesn't look worn too bad, are you sure you didn't have holes in your wires that were causing spark to jump?

Okay, NGK BPR7's are my choice and what I run 25lbs of boost on. As for your choices, I believe the Magnacore 8.5mm is a wire, and in that case that is the wire I use as well with no problems running 12.'s all day on them. I have also heard people bash the magnacore wire, but with the evidence that gsx951 posted, and the fact that many Turbo Buicks run them at 30 psi in 10-11 second cars, I have no problem with them at all. If he cut your plug wire, which I can't believe he did, after you put spark plugs in if the car isn't running good I would make him pay for replacement wires, because I think cutting into them would be a very bad thing. So get a good plug, gap it at .28 and the car should run fine.

If you are into audio, get the Magnecor because it is hands down the quietest wire.

If not, buy NGK.

If you do buy Magnecor, keep an OEM plug wire for setting your timing. Magnecor supress so well that inductive timing lights don't work.

You should go to www.magnecor.com and read. Steve has spent a lot of time posting tech info to help dispell myth and explain the science behind things.
This is your car.....

 

[92redman]

hmm, I didn't have any trouble using an inductive timing light on my Magnecors

Mine did not work at all.

ok well i decided to go with autolite cause advanced said they WILL work good and have warrenty and if they dont work i can drvie down there and yell at them... 50 bux for the set hmmm im getting the professional ones heres what they are... http://www.autolite.com/framer.cgi?page=http://www.autolite.com/products/proseries.htm for the plugs uhhhhh still on the edge people say i can get 7 range cold and just gap it lower then .32 (stock) and i wont get fouled beacuse it doesnt have time to burn carbon and stuff.. is this true if i put a 7 NGk at lets say .28 will it be able to keep from fouling and not misfire too?!

Wait, wait, wait...are you saying that the resistance of the wire has nothing to do with a strong spark? That is 100% completely incorrect. The more resistance in the wire, the larger the voltage drop. The more voltage drop in the wire, the less that's available at the plug.

The more resistance you have, the less current there will be in a spark, and the weaker it will be.

And the current alternating??...also incorrect. If it was alternating, then the coil wouldn't work at all. It would at that point be a transformer.

Talk about flunking science....this is high school stuff.

 

[SRiz]

UHHHHHHHHH! WTF everyone says different... the accell thundersports are the same price as the Autolite professional listed above WHICH ONE!?

I am sorry but voltage drop of the wires is nearly irrelevant. The stock coils are capable of producing way more voltage than needed to jump the gap and only supply enough to do so.

Accel Or Autolite!

 

[UrMyStlkAl]

I bought the Accels from Summit and got the NGK 7's from Pro Street. They work fine for me and those places were the cheapest I could find for both. Good luck

 

[Defiant]

NGK BPR6ES
.028"

Plug wires won't matter enough to worry about.

 

[SRiz]

i pulled my spark plugs cause i got a cylinder misfire on my ecu engine light code... so i took out my plugs and they all look like this ... there silver other then the last 3-4 threads and the electrode is white as seen in pic are these burnt to hell i am running 14psi? for reference there NGK Iridium BPR6EIX....i just ordered a set of BPR6ES stock temperature will this fix my misfire?

 

[Staytuned]

It might ...but I would throw in some new wires too while your at it.

 

[SRiz]

i was gonna get the accel thndersports got em for 50 bux meh not bad.... i had the magnacore 8.5 i didnt like em hopfully the accell will be better!

 

[Staytuned]

IMHO I wouldn't put Accel's on my lawn mower. I have had a couple sets on a previous ride and they both sucked ....miss fired all the time.
