M18*1.5 Car O2 Sensors Protective Plug Adapter Stainless Steel Engine Eliminator Adapter with Filter

This O2 cel fix actually has a miniature catalytic converter built inside and will help get rid of that annoying check engine light you get after modifying your exhaust or removing your catalytic converter, and sometimes even when installing a high flow catalytic converter. Don't take a chance on using an extension only as often they do not work, this is a real mini Catalytic Converter built into it.
