i had them on my truck for 2 years but recently got a tune so i dont need them anymore. the sims delete the error core/SES light when you either remove or hallow out you cats, i paid 120 for them and im only asking $55 shipped thanks Gene

 

will they be good for replacing 02 sensors that are bad? both mine are bad, i have been thinking of just doing sims. What do u think?

 

they work for the rears, and yes it will correct the code that says they are bad.

 

I will take them...how would you like to do this?

 

TTT bump

 

Will they work on an 04 4.3?
