Recommended Wires/Plugs, for our engines with Boost?

[Monello]

Hey guys, i was coming home from school today and was actually getting mcdonalds, so im waiting there, then all of a sudden my radio shuts off, im like ok, wtf, so then a second later the Service Engine Soon light comes on, i go home, hook up the Auto Xray, and it says Trouble Code 300, Misfire, 2/4 cylinder. So im going to be replacing the wires/plugs, do we need a heat range colder, or what, if anyone could recommend good wires/plugs for our boosted engines that would be great. I suspect that this is the reason my car has been idleing wierd, home its the problem =)

I run MSD wires... 8.5mm There is not big gain to be had there... The more effective item to change is/are the plugs...

I use the Iridium Plugs, NGK brand, from PFYC.com They seem to be very good, I have had no misfires ('cept for when I melted the wires that time). Iridium is supposed to run cooler in the motor than the average plug, while giving the same spark. So they are supposedly more durable plugs.

With boost and the increased heat from the blower... they seem to be a very good choice. I believe GM recently chose Iridium plugs as there primary style of OE plugs.

Well i guess im going to go for the iriduims, also do they come pre-gaped or do i gap them??? Let me know

[jaketuff]

They may come pre-gapped... but you would be better off gapping them properly yourself to our exact spec.

Alright bought the NGK TR55IX, now, what part number for the MSD wires? Are they the same as the GTP's? Let me know, going to hopefully get it done next week =)

[Craig99SE2]

I'd answer, but you'd prolly just slam me if anyone else disagreed ...

[Monello]

Before i actually had some respect for you, but after these past few days, this is all i have to say........

Unless your boosted get the **** off this forum.

Please save personal quarrels for PM's or e-mail; we don't want/need it on a public forum.

Stock wires and plugs should be fine; that's what the system was designed for. Check for vacuum leaks, as those can also trigger a misfire code.

[Monello]

Thanks mfuller, sorry but he is the number one reason that Spoon is leaving this website, he is sick of people like him who doubt everything that he says.

I tried to explain to Craig, that some people have different views and people arent always right, but he just responded calling me a newbie, and then posted on my thread about the wires and plugs.

... and who responded to your idle problem and helped you fix the problem by pointing you towards a vacuum leak? Hmmm ... who could that be ...

FWIW - ANY forced induction engine should be run with spark plugs 1-3 heat ranges lower than stock. The higher compression ratio produced in the combustion chamber requires less spark energy to ignite therefore requiring a lower heat plug. There is nothing wrong with higher heat range plugs, but seeing that they are metal bodied, they tend to "hold" heat and have shown to cause premature ddetonation in boosted engines.

Im sorry about the previous post, but you had no right to bash me and call me a newbie, i have done nothing but respect you and thank you for the help in the past. The post that was made about the motor mounts, if you read it, it isnt bashing you, just saying that people arent always going to agree on stuff, and some people are right and some are wrong. And sometimes we have to keep ourselves from saying things that could hurt or cause people to leave our site. I know that you know your ****, and help everyone with advice and new products, but when you introduce something new, be prepared for people to doubt its ability to work right or better. And Spoon has helped so many people with problems and advice like you have, yea he has been wrong on somethings but so have you, and so has anyone who is human.

Im sorry if the post about Motor Mounts, made you believe that i was bashing you, i seriously wasnt.

[Craig99SE2]

No problem ... likewise about the misunderstandings ...

FYI - See my post in Off-Topic w/respect to Spoon and dis-agreements ...

[jaketuff]

Whoa! This post has really done a full revolution...

Anyway, those are the exact spec that I use Monello. I have had no problem with them at all. I have autotapped the car and found that there is little issue if any with the ignition system's performance.

I have used the MSD Wires, and purchased them from APOC. I can't remember the sizing on them right now, but you may be able to find a lower resistance wire. So if you are looking to go all out, you can look at Magnecors. They are a step lower in resistance than the MSD.

There is little to be gained from the lowered resistance of course, but since the cost is around the same as the MSD, why not go for them. I would check with APOC, Aleroboy, he can hook you up and get the best wires. Just make sure as I said, to wrap the boots and wires appropriately on the left side of the motor. They must be protected from the manifold heat, they will melt the wires and lead to a misfire condition. It is the safe thing to do, and no one can really see the wrap on them anyway.

*Oh, have fun changing the fricking plugs!!!!

[Monello]

, is it even possible to change the front 3? or is the supercharger coming out? =/ Im also going to replace the hose that gones from the bypass valve to the supercharger as i suspect that its leaking. Tomarrow is going to be a busy day.

p.s. would any local places have the wrap to cover the wires? Are there different materials? let me know, thanks

Did I misss somthing?
Link to thread please
I dug arround and could not find.

Oh not to flame, but maybe spoon has been helpfull to you, but everytime I've actually tired to ask him a question, he would just ask me why I wanted to do that or go off on some deal about why I don't want to do that. Most of the time he had no clue what I was trying to do and was just trying to talk me out of what ever he thought I was talking about instead of just answering a simple question.

anyway I'm in the dark so someone plz fill me in.

[Dr_Kyle]

aleroboy, what part number do you use when you make the MSD sets for the 3400? is it 31189?

[aleroboy]

Actually if its red or blue msd wire I get it on a spool cut to length and put on the terminals and boots.
if its black I've used the 31183

Well, ignoring all the other garbage on here, I'll try to add a few things to help my bro.

I'm using the taylor plug wires from PFYC and Denso iridium plugs and they seem to be a good combination. In reality the stock ignition is very good. I just upgraded the plugs, wires, and coils to be on the safe side. My plugs are IT20's which are one heat range colder. The reason for this is to protect against detonation when running in very hot weather. Either NGK's or Denso's will work fine. When running boost/nitrous and creating higher cylinder pressures you actually need more spark energy (not less) because the higher pressure snuffs the spark. That is why iridium plugs are better. They resist heat more and spark easier. Combined with low resistance wires and more powerful coils that should be plenty. If you want a better spark still then add an MSD DIS-4 ignition box (just more expensive is all). The MSD is good for getting complete fuel burn to and increasing gas milage.

[Monello]

Hey, thanks for you reply.

I already have the NGK iridiums. Right now im just trying to figure out which wires will work the best. I hear very good things about taylor, and very bad. =/ So im just trying to figure out which would work the best.

[aleroboy]

I'm happy with the MSd's
