So my car is due for plugs, and the stock replacement iridium and CA emissions specific plugs are $15 each, even from discount sites. However, there are alternative platinums (which are also NGK just like OEM) for only $5 each.
I know iridium lasts longer than platinum, but I don’t plan on owning my car for 100k more miles anyway. So would I be sacrificing any actual performance by switching to the cheaper platinum plug? If the only difference means getting 60 or 70 thousand miles out of them instead of 100 then I would rather just save the $60.
