Coming home in the rain, having trouble getting around, reading your smartphone at an angle—I wonder if there are actually quite a few people like that?
The recently announced PRO-GRESS3 Wideband A/F Meter
has expanded its sensor boss lineup.
Additionally, sensor boss machining and installation service is now being offered, which is incredibly appreciated.
With this service now available, the barrier to installation has been significantly lowered.

I was a bit surprised by the product variations! Such generous specifications

What surprised me is that they’ve properly released bosses for smaller diameters as well.
It’s also really appreciated that you can choose between both stainless steel and titanium.
In this age of fuel injection dominance, if they cover all displacement ranges, sales will expand accordingly.
Compatible pipe diameter quick reference table

It’s a small thing, but a quick reference table that you can understand at a glance is really important.
The fewer confusing aspects when placing an order, the better, I think.
Please check the price and delivery time.
