This is a relatively new product from NGK. There's been quite a few group buys for them on another forum, but I haven't gotten any feedback on how they've held up to leaded gas. You're welcome to call the manufacturer, but anytime I ask an O2 sensor manufacturer for a hard figure on the life expectancy of running them on leaded gas, they just reply with something like "no oxygen sensor is made to run with leaded gas, so it will shorten the life expectancy" and refuse to give any rough figure. I'll post an inquiry on the other forum that's already done group buys on this product and see how they're holding up.
