M18*1.5 O2 Sensor CEL Check Engine Light Spacer Eliminator Adapter Oxygen Sensor Delete Kit

3rd gen 4Runner had CEL for faulty catalytic converter or downstream sensor. Probably one of those but I’m not buying either of them. I’ve got 320,000 miles and running strong. This adapter fit my 01 downstream sensor perfectly and now the 02 sensor is just far enough out of the exhaust stream.

I was surprised that this actually worked . To remove P0420 and 430 code . Even though it’s illegal in California. Some customer do not have $4 000 for new cat converters
