What are the correct oxygen sensors for a 99 boxster with a 99 3.4 liter 996 motor. Car has an FVD boxster S exhaust headers, sport cats, muffler with softronic tune. I am getting p1127 and 1129 codes. I was getting codes then they stopped when I had a bad MAF code. I replaced the MAF and now the car is running much better again, but the O2 codes are back.

Check that the fuel trim is operating normally before replacing the oxygen sensors. You may have a vacuum leak or faulty component setting the oxygen sensor codes. If you find they are bad, give our parts specialists a call at 1-888-280-7799. They can help you find the right part.
