Laura,

I had also tried another brand besides the Beck Arnely about $60 US, I
think it was STANDARD , but it failed after an 8 K mile tour of the US.

It gave up at 7K miles while I was climbing up to Denver. I was pulling
a trailer and had been running for two days and it was summer-- I  think
it was just the heat that got it.

The Vanagon's O2 Sensor is mounted to the front end of the Catalytic
convertor, a very hot location.

Sincerely,
