go to http://www.o2simulator.com to order.

i have one and it has been great for almost a year now.

 

on ebay there is a seller selling a part that fits between the sensor and the header or exhaust manifold(factory) that actually keeps the sensor out of the exhaust gas path and supposedly fools the sensor. I dont know if they work but id try it. They are just 9.99. Just letting you know.
