I have a marginal CAT with a P0430 code and think it may have gotten plugged up after my AOS failure a 1000 miles ago.

I just ignored the Engine light hoping it would eventually improve after using some Techtron additive but it has been staying on more than off.

I have a smog due in Nov so its time for action.

I plan to run some "CRC Guaranteed To Pass Emissions Test Formula" and replace the rear O2 Sensors, plus use some MAF cleaner.

Does anyone know the Brand Model number I should use for the post Cat Sensors, and a good source?

I'm confused by the array offered online that supposedly fit as OE and range from $24-$80.

Don't want to get an inferior or incompatible part.
