Interpol

I'm in the market for a wideband O2 sensor. I need one for some tuning work. My 8 has the RE-Amemiya intake box and manifold, high-flow cat, and exhaust, HKS ignition amplifier, and a Cobb AP. I recently was dyno'd and I'm running lean. It was suggested that I get a wideband and do some modifications to the maps.

So far I've seen the Bosch and NTK setups and I already trust those names, but I was wondering if there are other choices? Which would you guys suggest?

PLX is your first choice.
Innovate is your second.

I use a bosch 4.9 wideband o2 sensor.

I had a thread a while ago about my setup. Clicky.
