Air/Fuel Ratio Gauge
I asked this same question a little while back and got one of the Innovate kits.
Others here use them and seem to like them.
Look around though, because I got mine off ebay cheaper than you get it from Innovate.
I got my set for 156.99 shipped from this seller
dfactoryparts even though he has a low sales count and it was here within a week.
Brand new unopened factory box, and comes with everything you mentioned.
I posted all the info recently about sensors and locations, so give me a min to find it and I'll post the link.
Here is the post where we discussed the details about 1-2 sensors, and placement.
