Anyone have any thoughts on these in a stock truck....good or bad? Just fishing for thoughts...figured the iridium has a smaller electrode and would stay cleaner longer..more complete burn...better flame kernel .....:tup:
I just put a full set of UR5 ix in my typhoon. I used them because they were laying around/spares I pulled from my syclone when I first bought it. If it don't run right or burn out I'll use OEM copper core.
I have used Iridium plugs with much success. When I was really leaning on my stock motor and stock turbo 25+ psi of boost the Iridium plugs seemed to help with knock. I used the ur6IX plug.
