Hey all, I am in the middle of getting headers installed and need O2 sensor extensions for the rear O2 sensors of the headers. Does anybody know what size to get and where to get them? I went to the dealership and they said MB does not make extensions for their platforms.

Any help would be greatly appreciated! Thanks!
Oh, and this would be for a 2014 C63 507 coupe.

Dodge makes some extensions. Not sure on what model. Try Napa too. Bring an O2 with you.

Or cut and solder longer wires in.

Mhp or mbh should know exactly.

I think Bosch makes them as well, but not sure if they will fit.

Bump. I'm struggling to get an answer. I shot MBH a couple notes but no reply. He must be on vaca or something.

Give MHP a call. I received 02 extensions when I purchased my arh/mhp headers last year.

Yep, MHP headers come with extensions - so they obviously know which ones fit.

Thanks guys! I was able to find some on eBay as well from a vendor.
