I've got a new header and downpipe for my 7afe but the header has the boss for an O2 sensor my car doesn't have. Is it ok to move the one from the old downpipe to the header?
Need some help its my first car and have no experience with anything other then electrics yet

The only real issue with having the O2 sensor where it is pictured on the aftermarket header is that it will only read issues present in the one cylinder. The stock O2 sensor is placed in the lower pipe in order to read the exhaust flow from all cylinders.
The whole point of the sensor is to give the ECU the information it needs to maintain the engine in good running condition. Using the sensor in just one runner of a manifold means you're not giving it 75% of the information it should receive. |
