I want to fit an 02 sensor to check my Air/Fuel ratio's on my 2.1 Zetec with 45 dcoe's and get the right jets rather than rely on emissions.

So is there a kit where a sensor can be fitted without the need of welding a bung to hold the sensor, to my 4 to 1 Stainless manifold which fits to a 6" can. There's only approx 2" of pipe between the 4 to 1 into the can.

thanks
