Denso Iradium, I used these before and love them! I got them pretty cheap from frank2.0l, if i didn't get it that cheap i would have gone with NGK Iradium

you paid $50 for 4 plugs? lololol

i think i paid $3 each

 

NGK Platinums in the OE heat range.

 

NGK Iridiums.

I read somewhere that they were better for longevity, and helped on gas mileage.

Not sure though, I can't tell in performance, but I pulled all four to check the burn after 1500 miles, and they all looked exactly the same.

A nice clean hot burn, no carbon build up, and almost no wear on the ceramic, or tips.

As for gas mileage, I can't tell that either, but they do burn hot as hell.

Yes, Really

 

NGK Iridium ZFR6FIX-11
In Russia (where I'm from) they cost about $40 (4-pack)...

 

so by having more ground straps you get more spark ? The spark is only going to jump to the path of least resistance.

And if your assumption was correct why dont you see many ppl running around with bosch plugs ?
