does anyone know how to convert the hx 5 band O2sensor to the EX 4 band o2 sensor. i changed intake manifold on my car to the ex which elimitnayed the egr vavle. so all i have left now for my car to run smoothly is to get an o2 sim or fouler for the secondary o2 sensor and i have to convert my 5 band o2 sensor to 4 band. i tried search but nothing came up really i guess n one never had this problem since only a few peopel have hx cars
