I got the NGK Iridium 4919s. They are supposedly for an NA, but the only difference between the NGK Iridiums for NA and turbo is the spark plug nut size, and the turbo plugs don't fit in either car...NGK=dumb. The plugs are good though. They are gapped correctly out of the box I believe. Even if they aren't, my car runs perfectly and I did nothing to them.

yea i always wondered what the hell was wrong with NGK! the parts store tried to tell me i dont have a turbo den..i said die!:anger: :anger:

amm so should i chose plat or IRD ?
and guys what about gaping ?

 

[BARTON]

They come pre-gapped. I just checked mine and put them in. Each of them was perfect, but I would always recommend double checking the gap. I like the iridium for my set-up.

Whats your setup and howmuch psi ?

and how many miles you change them >

 

[kevman05]

i really prefer the V POWER PLATS they run hard, but they burn out quick.

they are pre-gapped for you, just drop them in.

 

[bahraini_zupra]

Oh and by the way how much the gap should be >?

 

[bahraini_zupra]

U mean the platinum ? ive heared platinum last so longer than IRID ?

 

[kevman05]

for some reason my PLATS burn out quick, im runnin 10 lbs of boost. Dont know how many miles, my speedo doesnt werk, but takin it that i drive my car hard even single time i drive it...that may be the reason.

i dunt kno about the gap...i just use the gap that come in the box. but if memory serves correct..i think .28 is the gap...can anyone verify?

 

[lamer5]

Just get the Iridiums I mentioned above, they last a long time at high boost (I'm running 15psi). The gap is correct on them from the box.

I've been told that just trying to measure the gap on the platinums will destroy the platinum coating on them, which is why they come pre-gapped.

Anyone able to give this a yea or nay?

wrong. platinum and iridium are some of the hardest metals on the earth...little chance you can scratch the coating off. HOWEVER...it is a BRITTLE material, so if you gap them, then move them again...they might break right off.

why waste the money, copper plugs own...

That is what i thought about these metals....I believe mine said to have the Gap set at 42....I am guessing but there was a # 2 at the end.
if I find the specs, ill let you know Bahraini
