Why NGK Iridium? More Durability and a Higher Melting Point compared to Platinum, better center electrode anti-oxidation and anti-erosion, improved ignition, superior anti-fouling, lower required voltage, new metal shell plating process for better anti-corrosion. NGK Iridium One Step Colder plugs are recommended for cars with heavy modifications. These NGK Iridium plugs will get your Supra running smoother and free up some power through increased efficiency and increased heat resistance.

Please Note:Iridium plugs are able to use larger gap setting with less voltage. Some customers choose to regap these plugs to correct misfiring or tune for optimal spark -- do so at your own risk -- slide-type plug gapper will damage the fragile iridium tip.
7MGTE Turbo Motor ONLY.
Price is per plug- for a complete set you must order 6 plugs.
Shipping costs are calculated upon checkout



So I need new spark plugs and these are the kind I want to get. Now do these come pre gapped? If I try to gap them I will jack em up. Miss fire?
Do any of you guys run these spark plugs? If so how do you like them and do any of you regap them, if so how?

Go coppers, better for heat dissipation, better for turbo cars.

Do not adjust the gap on iridium plugs. If you want the ones with the stock gap for a turbo, that would be:
NGK Iridium spark plug 5689 BCPR6EIX .032

other NGK plugs:
NGK Platinum plugs 5275, BCPR6EP-N-8, .032
NGK Traditional spark plug 2330 BCPR6ES .032

Damnit man!!!

I put my irridiums in today and I regapped them. They were gapped to .030 and I wanted them gapped to .026. My NGK 6097's won't run right unless I gap them to .020, so I thought that the .026 would be good enough for the irridiums. I may have damaged them but the car idled ten times better than it had been. I'll see how they perform under wot.

Charles, can I order some with a smaller than .032 gap?

Can be gapped but you have to be very careful NOT to touch the centre electrode.

I had problems with them glowplugging at high boost sustained top end pulls that went away with the same heat range/gap coppers.

What is glowplugging? I definately touched the center electrode cause I'm a dumbass and didn't know any better. There went $45.00 shot up a wild hogs ass.

What copper plugs do you run IJ?

The USD is no where near where it was folks.....

It has lost value against every single currency out there.

That said, forget Iridium, Copper plugs unless you are running a very "hot" system (voltage wise).
