Hey brothers and sisters, saw these HKS iridium spark plugs wondering if there is a difference in performance between these and the NGK ones. The reason I'm asking is because the HKS plugs are about 25 dollars more... each...lol
opinions are welcome!

I went with the GReddy/NGK ones because I have had better luck in the past with NGK. (and i bought the GReddy ones just cause they say GReddy on them ) I've also had a couple of sets of the HK$/denso plugs in the past, nothing but bad times.
