High hydrocarbons on my last emissions.I am about to change the plugs, o2 sensors and CTS.I dont plan on going to the dealer.Have you guys ever bought these items from Autozone, Advanced or Napa?I would prefer Denso 02 sensors.

Bought the direct fit Denso O2's from Amazon. CTS was from dealer. Hard to not get some Chinesium part so for the CTS, buy what the budget doesn't mind.

Looks like Rock Auto has the parts #s.I just dont know which to get for the denso..Most of these Ebay sensors dont wokr well.Less Ohms and all kinds of crap.I am thinking Am,,azon may be the same.My last CTS was from Advanced , and I think I need to stay away from there

Stay with dealer CTS....more expensive but accurate.
Remember to obtain new crush washer and plastic connector shell (not pigtail) on wiring harness side as they tend to be brittle and break.

The contacts extract quite easily from the old connector shell by using a fine pick to open the locking lances and then snap-fits into new shell.

Your dealer can assist you there.
