Default Denso O2's, please help.

Okay guys, I have longtube headers and I'm convinced that my o2's are the reason why I am getting bad gas mileage. I plan on getting Denso O2's from sparkplugs.com. Now which one's do I order, such as OE Identical vs Universal and which Front and Right O2's do I get because there are 2 different kinds.Also, will the o2 extensions I have on my car now connect okay with the Denso's? I would be getting front o2's to connect the extensions with for my longtubes correct?

If someone can help me out asap, I would like to order these today or by tomorrow morning so I can have them by the end of the week. Thanks!

I've done research on those and they don't seem to last long and tuners don't recommend those.

The diff from the rears and fronts are a longer wire. I went to the denso because the are a little more lead tolerant than others, and easier to clean. The GN guys have been running these for years. If there is a differance please tell me.
