I am changing the exhaust on my C4. The old Lsmbda sensors were wotking, but they are going to come out of the old cat in one piece. Any experience of aftermarket sensors of is it best just to go OEM?

Just had Bosch fitted to mine and no problems.
Got them from Top Gear when I bought my exhaust as they came up as an option when making the purchase can't remember the exact cost think they were about £85 each.
 
Thanks for the replies. I'll source some Bosch ones when I'm ready to fit them.

Forgot to say that one of the old sensors was removed just to make absolutely sure the Bosch replacements were the same.

The new Bosch ones looked exactly the same as OEM.

Cheers
Stu.
