yes, AC's are about $130 ea, and Denso's are $49 ea (but I get a good deal on the denso's from a local part store) And of course both brands are the 4 wire heated sensor's. The AC's have slots in the sensor tip, and the Denso's have holes in the sensor tip.
Personally I think the Denso's look alot more quality made. (but that's a Japan made part for you.)

ya that's cool. Hey you woulden't happen to have any LT's for sale for my 94 Z?
Also do you know about how much rwhp a set of hooker LT's would add? Of course with a k/n cai, granitelli maf, ceramic elbow, and 58mm TB with the manifold ported to match the 58mm. Also had a hollow 3 inch pipe for the cat & mandrel bent 3 inch cat back with flowmaster.

Denso's are great replacement sensors and have a higher tolerance for leaded race gas also. Go with OEM if you can spring the cash for them. For the price difference I would replace mine with a Denso or an NTK sensor.

I would go with with Denso and replace them more often, O2 sensors are kind of like plugs and wires they might not be bad but when you put on a new set you can tell the difference. Let me know how your car runs with the new sensors.

i know with long tube headers, Bosch O2's are really popular because they are longer (designed for vettes). the part number for them is 13111.

Yes I agree but what part of asia. Lots of junk comes from China, Twain, etc. Most all things made in Japan are the highest quailty parts you can find. Why do you think Honda cars are always rated #1? I am not saying I love rice grinders because i don't. I feel bad for those poor hondas that get the crap beat out them. I love CAMAROS no doubt about it! But my daily drivers are Hondas and Toyotas.
P.S. Thanks for all the feedback on the o2 senser ?. I went with the Denso sensors. I haven't drove the car more than a few miles since the install of them. Due to bad winter weather in Utah.
Thanks again,
Scott...
