i think all the o/p is sayin is "does gap make a big diff" ...a simple yes is nice...lol

 

ditto then... ill stop with my info knowledge and just give dumb answers from now on

 

..thats not what im sayin...info = great...but u r makin the man feel like a retard...

 

i didn't say it, somene else did if i didn't want to learn i wouldn't have asked

but i appreciate the info. it's nice to get real answers when you don't know something.

 

there is absolutely nothing wrong with a car that runs iridium, it is much easier to produce a spark with the iridium plug, plain and simple.

 

when you ask a question.. do you argue with somebody giving you an answer?

typically not.. so when you do argue.. what is gonna happen..

its like fighting with the hand that feeds you..

not trying to make anybody feel retarded, but dont assume b/c you can do something that you know everything about it... trust me.. you can pull all the "pictures" of how plugs should look and what not.. and i can tell you there is more reading done to it...

you see level X of plug reading from 99.99999% of things on webpages/books/mags/word of mouth and what not..

old buddy of mine use to work for Petty Interprises in the R&D department.. trust me.. alot more to plugs then what "meets the eye"

not bashing.. just saying... i myself would have no idea either if i wasnt shown by him too.

you must have reading comprehension problems...

no where in any statement did i say Iridium were bad for a car.. i just said they were not the BEST for the car

if a statement made you think i was putting iridiums down, then you were mis-understanding what i was saying.

look up conductivity of copper plugs for iridiums plugs and get back to me sport..

 

ok, i do understand this...i didnt mean to **** you off...geez....im just sayin, its great to know that we could learn so much about our plugs....but here is what i would do...if i was a master of plug knowledge..lol:

i would say, hey...when i pull a plug, i look for this, this, this, and this...just some common stuff that us beginers might need to know...and then let the more advanced questions flow from there...

trust me, i (and im sure we) appreciate the knoledge...but personally making a list of stuff i can do without telling me how to do a little of it makes me feel like u are tying to tell me that i dont know anything...so, please, more info on tha what we should look for when we pull a plug idea...i appreciate you input very much

 

Man you are pretty full of yourself aren 't you.

You said that if his car runs better with the iridium there is something wrong, maybe not big but something. That is a general statement thats means nothing.

I can comprehend trust me, you just seem to be saying the exact same thing, when in reality an iridium plug is actually a great thing for our cars considering it naturally runs "cooler" then the copper

I know conductivity now you go look up the anatomy of an iridium plug and a copper plug and tell me which one will produce a better spark and which will be much easier to produce. Iridium wins.

Do not treat me like a moron, if you would prefer Ill start dropping my credentials



Im trying to lay down information just like you, an I do know what I am talking about aswell. Just stop putting people down and being so touchy when I wonder why you say something that is far from the truth like "if your car runs better with the iridium there is something else wrong"

 

copper sparks a hell of a lot easier, but yes, ir plugs will last a while longer.

i use the AC delco professional IR plugs in mine, and change them once every 15k or so. runs great.

 

Wrong the anatomy of the iridium plug allows it to spark easier.

yes copper of the same style tip would spark easier again but it wouldnt last because of how weak it is compared to iridium. Please go reasearch and you will see

 

ok, here's a few video still i took

 

lol @ Dust...

You just went and picked through your trash!!!

 

Advantages of Iridium spark plug types
Due to the properties of Iridium, the spark plugs centre electrode can be made with a much smaller diameter than with platinum, Gold or gold palladium and copper/nickel types without sacrificing service life. The spark plugs potential difference is more concentrated at the tiny Iridium tip and hence less 'spark jump' voltage is required - this can be as much as 5,000 volts less than with standard plug types. Ignition is improved and less strain is placed on the ignition system. Benefits of improved ignition/combustion include better fuel economy, increased power/acceleration and especially better throttle response.



here is a little blurb from our product catalog that supports my point

 

no, i had them in the car still

still waiting for the analasys on the plugs

 

I tryed both copper and iridium plugs. Big difference with the iridiums. Not saying that it is for everyone, but my car loves them.

 

Ok, no-one that I can see seems to have giving the answer to the question of why an increase in gap doesnt "seem" to make a difference. Its pretty simple really, your coil puts more than enough voltage to fire your plug at the regular gap. When the gap gets bigger excess voltage is availible to ensure the spark still jumps the gap. Fact is at most factory gaps, a voltage of 10,000v is usually the required voltaged to start the spark, your coil is capable of putting out (depending on style,manufacturer,etc) is somewhere from 30-60,000v. Hence why an increase in gap doesn't "seem" to make a difference in the engine.

 

D4u2s0t, What kind of tune are you running? I don't see anything wrong with the plug, gap does look a little large though, when i took my stock ones out they were pretty blackened comparably (stock .039 gap). And when i took the ones out of my 122000 mile protege the copper electrode was wearing away and it was pretty f***ing black as well. I barely see any residue besides some whiteness on your plug which means it was probably running hot, someone more experienced please chime in.

I only started looking at differences with plugs for my motorcycle and getting that thing tuned up correctly but its carburated and from what your plug looks like i'd say you were running too lean if it were a carburated engine, but fuel injected and forced induction i dunno what would be happening exactly or what signs there would be from improper gap sizing.
