Hello,

I have an Invidia O2 housing and QTP downpipe that I have not installed yet. My big question is if the donut gasket that comes with the QTP downpipe will work with the Invidia O2 housing with a slight gap. I will try to attach a pic to show what I'm talking about. The Invidia donut gasket definitely does not work, as it is too small.

On a separate issue, I understand that the O2 sensor is too short to reach the Invidia housing and requires either unwrapping the sensor loom to get more reach or buying some sort of electrical wire extender? I have never seen this item before?
