K&n+o2=pwned?

Today the check engine light came on, so I brought it to the dealer. They checked it out, and they say it was the O2 sensor and needs replacemenmt. Could the K&N filters have effected this, or is it just the milage of the car? Does keeping a broken O2 sensor matter? Or can I run the car without the sensor? I feel the car rev's more freely, but I just might be thinking that

o2 sensor is in the exhuast. K&N filter wouldn't have anything to do with it going out.

How many miles on your car ? o2 sensors usually get replaced every 60,000-100,000 miles.

I've got: 67000 Km= 41631.9 Miles. Does this in any way effect my engine or damage any other part of the car if not replaced?

Had mine replaced at 75K mi. I don't they will cause much damage to your engine but it can affect performance since they measure and report O2 amounts in the exhaust.

what happened to me when i didn't get my front 2 O2 sensors replaced was the car not accelerating properly, and the car idling really rough. The bad thing is that in California, you will not be able to pass smog w/o replacing them.

Up in Canada we call "smog" "aircare" and I passed it just last week:p I tested my car yesturday with the Gtimer, and my best run was 0-60mph in 6.38s with 1 passenger. So far I dont think the O2 sensor is affecting anything. Ill get it replaced this summer once I get new headers
