WTB Oxygen gauge and sensor kit

hoping to strive for better tuning.

For one of many http://www.aemelectronics.com/?q=products/...-uego-afr-gauge

I wonder if there is a quality difference between the AEM and the APSX-D2 (Which is $30 cheaper?)

Note: I saw a picture of the APSX kit on ebay and it showed it using a Bosch O2 sensor.

Is your avitar a Cherokee or a Warrior?
I earned my Private ticket in a Warrior 160hp and have very fond memories of that plane. (Flying a Comanche 180 now.)

It's a 1972 Piper Cherokee/4 place/140..........long gone

Here is a post I found on a search:
