This is a great idea and it works perfectly! If you have an oxygen sensor for your wide band kit that you need to install, you have now found out that you have to find a welder who can drill the hole in your exhaust or down pipe, then weld in the bung. Sometimes, this has to be done off the car, so even more of a hassle.
Why do you need this, and how does it work? Simple, most people can drill a hole, but not everyone can weld. With this kit, all you do is drill the correct size hole, and use the AEM no weld kit and clamp on the oxygen sensor fitting.
It is simply the best thing since sliced bread. Holds pressure to 50psi--as if any exhaust system will reach 50 psi. Remember, exhaust is after boost, so it might hit 2 psi.
You will receive stainless steel clamp kit, high temp sealer, and the O2 sensor bung without O2 sensor.
