Damn Mystery Denso Plugs!!!!!!!!
I have a 99 gs300 and I cant find any forums stating the correct denso iridium plugs. I bought denso iridium ik16 today but I have seen a post where someone said they put sk20 in there 99 gs300. So what is the correct plug and why does someone say that the Iks will only get 30K opposed to the Sks? Does that go for the Ik16 vs Sk16s to. Can I put SK20s in? Will they last longer? Whats the deal?Why does the gs400 get 90k and the gs300 only get 60K? WHAT DO I NEED?!!!

I think the OEM GS300 plug is a SK16. The IK series are more for aftermarket and modified engines. IK series has a thinner center electrode (supposedly for a bigger spark and less resistance). The downside is that the IK series doesn't last as long due to the thinner electrode. Just stick with the SK16 and you'll be good to go
