Pacesetters & O2's
 

Ive read somewhere that the coating on the pacesetters ruin O2's. Can anyone verify this? Any input will be appreciated.

No. But the stock o2 sensors are known to basically fuck up. Most people go with the Bosch 13111's when the stockers start to throw codes.

What he said.

Any header will do it. They're right, it's the O2s that are the problem, not the headers. :judge:
