I've have a 1999 accord DX 4 door. Its been unreal for 15k, but now needs a catalytic converter. Anyone know the cat and o2 sensor that will replace these parts? I plan to by buy online and do myself.
Thanks.

 

Suggest checking ebay for direct fit replacement parts.

OEM converters are pretty reliable and rarely fail. Why do you think yours needs replacement?

O2 sensor's are relatively cheap and should be replaced around 100K miles or so.

good luck

 

Well, I have a check engine light (P0420 Catalyst System Efficiency Below Threshold). Put in a new air filter then reset light. Lasted a few weeks now is back on. Mechanic confirm it needs a cat. I'll check ebay. What do you think?
