Can someone explain the difference b/t the 02 simulators and mechanical 02 fixes that will prevent the cel from occuring when you install a test pipe. I'm going to do the install next week and need to know which I should go with.

Thanks.

 

simulator is an electric fix. the other is mechanical (pulling the o2 further out of the o2 bung and exhaust stream)...

 

for the $$ and ease of install (provided ur o2 sensor comes out FAIRRRLY easy) i would use the Spark Plug anti-fouler method u can find in the how to section

good luck,
mike
